Spectroscopy and Laser Applications

Abstract The infrared spectra of 2-chloro, 2-bromo, 2-iodo and 2-cyanopropane (the isopropyl halides and isopropyl cyanide) were recorded in the gaseous and liquid states in the region 5000–200 cm −1 . Raman spectra of the liquids were obtained using He-Ne laser excitation and semiquantitative polarization data are reported. The vibrational spectra of these substances are very closely related and the spectra are interpreted in terms of C s , symmetry for all the molecules. A tentative assignment of the fundamental frequencies for each compound is proposed.
