2014年8月9日 · • Infrared Spectroscopy (IR) – Triggering molecular vibrations through irradiation with infrared light. Provides mostly information about the presence or absence of certain functional groups. • Mass spectrometry – Bombardment of the sample with electrons and detection of resulting molecular fragments.

Infrared Group Analysis A. General The primary use of the IR is to detect functional groups Because the IR looks at the interaction of the EM spectrum with actual bonds, it provides a unique qualitative probe into the functionality of a molecule, as functional groups are merely different configurations of different types of bonds Since most ...

INFRARED SPECTROSCOPY (PART-1, PPT-7) Introduction Infrared (IR) radiation refers to that part of the electromagnetic spectrum between the visible (400-800 nm) and microwave regions (1.0 -10 cm). IR spectrum contains a large number of absorption bands and it is impossible to assign all of them but those can be assigned correctly

2014年3月29日 · The document discusses infrared (IR) absorption spectroscopy. It begins by defining IR spectroscopy and explaining that it deals with the infrared region of the electromagnetic spectrum. It then discusses the different IR regions and how IR radiation causes molecular vibrations when it hits a molecule.
