The IQ Academic Spectral Database offers a convenient collection of infrared and NMR spectra of organic compounds relevant to college introductory courses on organic chemistry and the supplementary laboratory courses on experimental organic chemistry and qualitative organic analysis. In addition to serving as a teaching aid, this database can used by teachers and students in their research activities to establish the identity of compounds in the laboratory through empirical comparison via functional group analysis.
The database includes IR and NMR spectra for nearly 1,300 specially selected compounds that cover a broad range of chemical classes useful within the chemistry curriculum. Each compound contains cross-referenced spectral data for IR, 1HNMR, and 13CNMR and value-added information, such as technique, molecular formula, molecular weight, CAS Registry number, melting point, and boiling point.
Search by Spectrum, Peak, Structure, & More!
The IQ Academic Spectral Database works within Bio-Rad's KnowItAll Academic Edition, which is a free software package for teachers and students. With the KnowItAll Academic Edition, you can import your own data and search against the IQ Database. Searches are customizable and are driven by powerful algorithms. Search by fields such as name, structure, substructure, properties, and analytical data, such as spectra and peaks. The KnowItAll Academic Edition enables users to draw structures in 2D and 3D,perform IR and Raman functional group analysis, process and search IR, NMR, and Raman spectra, generate high-quality laboratory reports, and more!
High-Quality Data Students Can Afford
With the IQ Academic Spectral Database, students and teachers can affordably access high quality spectra used by major companies and research institutions throughout the world. Data for the IQ Academic Spectral Database was carefully chosen from the best spectral reference sources available:
- Infrared data was selected from Sadtler's high-quality, comprehensive collection
of reference spectra.
- The NMR data was provided by the National Institute of Advanced Industrial Science and Technology and NMRDBTech, Inc., Japan. The 13C NMR spectra are 1H decoupled 13C NMR spectra and the 1H NMR spectra were measured at 90 and/or 400 MHz and contains generated 300 MHz spectra.
These data sources come together to form a database that is ideal for teaching.
The IQ Database has been processed according to the Sadtler Data Review Protocol
to provide students and teachers with the highest standard available in spectral
data today. These rigorous qualifying procedures start at data acquisition and continue
throughout the database development process. Every effort is made to maintain our
protocol's high standard of accuracy before placing a spectrum in a collection.
Link Directly to Sadtler's Renowned Spectral Handbooks
Each spectral record in the IQ database contains a web link to supplemental information on that compound or class of compounds from Sadtler's world-renowned spectral handbooks. These essential handbooks for IR, 1H, and 13C NMR are useful for spectral interpretation as they highlight pertinent peak information to distinguish between chemical classes.
- The Sadtler Infrared Spectral Handbook - The infrared handbook contains a
table of correlations and absorption band locations to help students and teachers
to identify a compound as a member of a specific chemical class. The listing of
the correlations and absorption band locations appear in decreasing order of diagnostic
value. The first listed absorption feature is considered to be related to the most
important atomic linkage in the particular functional group or structure. Absorption
bands assigned lower numbers are considered to be of secondary importance, but necessary
for confirming the identity of the primary absorption band and defining it as part
of a specific functional group or carbon framework.
- The Sadtler Proton NMR Spectral Handbook - The proton NMR handbook records
the chemical shifts exhibited by spectra as determined by the shielding or deshielding
effect of the functional groups. Using a ppm delta scale (TMS = 0.0 ppm), these
shifts were read from the original calibrated NMR charts and are considered accurate
to within ± 0.05 ppm. The majority of spectra in the handbook were generated using
one of six common NMR solvents and were selected in the following order of preference:
carbon tetrachloride (for liquid samples), deuterochloroform, Polysol (50% CDCI3/50%
DMSO-d6), dimethyl sulfoxide-d6, D2O, and trifluoroacetic
acid. A limited number of samples were scanned as solutions in undeuterated acetone
or undeuterated dimethyl sulfoxide. Because of the importance of solvent effects
on proton chemical shifts, all tabulated data list the solvent that was employed
to record the spectrum.
- The Sadtler Carbon NMR Spectral Handbook - The carbon NMR handbook also presents the chemical shifts exhibited by the groups of spectra. These shifts were read from the original calibrated NMR charts and are considered accurate to within ± 0.05 ppm. They contain the chemical structure or substructure as well as the solvent.
