The infrared spectrum of polyacrylonitrile typically shows absorption peaks associated with C-H stretching vibrations, C≡N stretching vibrations, and N-H bending vibrations. The exact peaks and intensities can vary depending on the molecular structure of the polymer and any additional functional groups present.
The toxic gas released from polyacrylonitrile is hydrogen cyanide. It is a highly toxic and flammable gas that can be released when polyacrylonitrile is burned or exposed to high temperatures. It poses a significant health risk if inhaled.
Infrared spectroscopy is a powerful technique used to identify functional groups in unknown compounds by measuring the absorption of infrared light. By comparing the peaks in the infrared spectrum of an unknown compound to reference spectra, the functional groups present can be identified. This information can help in determining the molecular structure and composition of the compound.
Infrared spectroscopy identifies organic compounds by measuring the absorption of infrared radiation by the compound's functional groups. Each functional group absorbs infrared radiation at specific frequencies, which produce characteristic peaks in the IR spectrum. By comparing these peaks to reference spectra, the functional groups present in the compound can be identified.
Polyacrylonitrile, Acrylonitrile butadiene styrene
Frequently used are polyacrylamide/polyacrylate copolymers, polyethylene oxide, polyacrylonitrile etc.
There are three main types of infrared spectra: absorption spectra, emission spectra, and reflection spectra. Absorption spectra are produced when a material absorbs infrared energy, emission spectra are produced when a material emits infrared radiation, and reflection spectra result from the reflection of infrared radiation off a material.

To interpret infrared spectra effectively, one must analyze the peaks and patterns in the spectrum to identify functional groups present in the molecule. This involves comparing the observed peaks to known values for different functional groups and considering factors such as peak intensity and shape. Additionally, understanding the principles of infrared spectroscopy and practicing with a variety of spectra can help improve interpretation skills.
