You may find a wide variety of information from the Internet. Carefully choosing and using the Internet resources can be very beneficial to your research.
Be aware that information on the internet is not regulated for quality or accuracy, so it is important for you to evaluate the source. Try the evaluation criteria on "Evaluating Sources" to decide when it is appropriate to use that information.
Web resources can be web pages and documents on the internet that provide useful information.
Examples include:
Recommended Web Sites for Spectra and
Spectrum-related Information
This site includes information on a wide range of spectroscopy topics, including NMR, IR, UV and mass spec. Access to some features, such as the online e-zine Spectral Lines, requires (no-cost) registration. This site includes discussion forums and links to other spectroscopy-related websites, including online databases of spectral data.
This site can be searched by "lines" (Spectral lines and associated energy levels) or "levels" (energy levels), and also includes a table of ground states and ionization energies for neutral atoms. [Produced by the National Institute of Standards and Technology (NIST)].
Includes IR, mass spec, and UV spectra for thousands of compounds. Scroll down to "Documentation."
Maintained by the Japanese National Institute of Advanced Industrial Science and Technology, this database includes NMR, IR, and MS data for tens of thousands of compounds. Access is free. The providers request that users not download more than 50 files per day, and that you acknowledge them if any data are used in a publication or presentation.
SDBS is an integrated spectral database system for organic compounds,which includes 6 different types of spectra under a directory of the compounds. The six spectra are as follows, an electron impact Mass spectrum (EI-MS), a Fourier transform infrared spectrum (FT-IR), a 1H nuclear magnetic resonance (NMR) spectrum, a 13C NMR spectrum, a laser Raman spectrum, and an electron spin resonance (ESR) spectrum.
The lectures on physics by Richard Feynman, given in 1964 at Cornell University and are available now online for free here.
Lecture titles are as follows:
Surely You're Joking, Mr. Feynman! by 
General tips for success in physics courses and college in general.
Large database of resources, formulas, and examples for all levels of physics.
Digital versions of the extremely popular books by Feynman, Leighton, and Sands. These books are adaptions of lectures given by Feynman at Cal-Tech. They cover material from both semesters of (calculus-based) physics.
Free online textbook for both semesters of physics (both algebra-based and calculus-based).
Helpful resource containing many answers for all levels of physics-related questions. Quote: "Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics."
Khan Academy is a library of free online video tutorials, worked examples, exercises, simulations, and other learning resources.
Dr. Walter Lewin was a professor of physics at MIT for many years. These lectures were recorded as part of MIT's Open Courseware (OCW) project and cover both semesters of (calculus-based) physics.
Julius Sumner Miller was an Australian physicist and educator. These lectures were recorded for an Australian television program and contain many experiments, demonstrations, and explanations to illustrate various physical phenomena.
Dr. Mats Selen is a professor of physics at the University of Illinois. These videos were recorded as part of a public-outreach effort by the Illinois physics department. Though somewhat disorganized, they contain many interesting experiments and demonstrations.
A library of interactive physics simulations for all levels of physics.
"AIP's Center for History of Physics works to preserve and make known the historical record of modern physics and allied sciences." Under the "Resources" menu, the website provides online exhibits and oral history interviews. The "Array of Contemporary American Physicists" links provides biographies of American modern physicists, a list of related institutions and topic guides.
"An archive presenting and documenting some important and original contributions made before 1976 by 20th century women." Although this site is rather dated (copyright 2001), it provides very useful information on women physicists of the 20th century.
Eric Weisstein's World of Science is an encyclopedia for physics, astronomy, scientific biography, and chemistry. Click on the physics icon to search and browse this resource.
"With a library of over 3,600 videos on everything from arithmetic to physics, finance, and history and hundreds of skills to practice."
Physics Central includes information on physics topics and news.
"Physics Today Online serves as Physics Today's home on the Internet, presenting the magazine's digital edition and continually building a valuable online archive. In addition, PTOL extends the magazine's coverage of the physical sciences with the daily edition, unique online content from our editors and contributors."
Search physics.org's database of 4,000 physics websites. It also includes feature articles and commonly asked questions.
"The PhysLink.com is a comprehensive physics and astronomy online education, research and reference web site."
Includes facts, articles, and video interviews and lectures.
