An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.
The method or technique of infrared spectroscopy is conducted with an instrument called an infrared spectrometer (or spectrophotometer) which produces an infrared spectrum. An IR spectrum can be visualized in a graph of infrared light absorbance (or transmittance ) on the vertical axis vs. frequency , wavenumber or wavelength on the horizontal ...
The phases of volatiles also give different frequency of bond stretch and eventually produce a specific wavenumber. For example, the band of solid and liquid CO 2 occurs in between 2336 and 2345 cm −1 ; and the CO 2 gas phase shows two distinctive bands at 2338 cm −1 and 2361 cm −1 .

Fourier transform infrared spectroscopy (FTIR) [1] is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range.
Dog parents are perpetually curious about their dogs’ behaviors, whether they are amusing or slightly perplexing. For example, we often wonder, why do dogs stretch so much? In this guide, we ...
Absorptions bands in the Earth's atmosphere created by greenhouse gases and the resulting effects on transmitted radiation.. In spectroscopy, an absorption band is a range of wavelengths, frequencies or energies in the electromagnetic spectrum that are characteristic of a particular transition from initial to final state in a substance.
A comprehensive list of discriminatory acts against American Muslims might be impossible, but The Huffington Post wants to document this deplorable wave of hate using news reports and firsthand accounts.
