Infrared spectra of methanol, ethanol, and n-propanol - NIST
nvlpubs.nist.govfirm the assignments for methanol and to study and assign the vibrational spectra of ethanol and n-propanol. 1. Introduction The infrared absorption spectrum of methanol in the vapor state was measured by Borden and Barker [l] l with a gratin g spectrometer. The stronger bands were resolved so that the rotational structure was apparen t.
Vibrational-Rotational Spectroscopy
web.mit.eduSo, the vibrational-rotational spectrum should look like equally spaced lines about ν0 with sidebands peaked at J’’>0. ν 0 • Overall amplitude from vibrational transition dipole moment • Relative amplitude of rotational lines from rotational populations In reality, what we observe in spectra is a bit different. ν 0 ν
