Analysis of CO2 bands near 2600 cm-1
Abstract:
The collision-broadened linewidths and band intensities of three overlapping CO(2) bands near 2600 cm(-1) have been determined from spectra obtained with a Fourier transform spectrometer. These spectra have SNRs in excess of 500 and a spectral resolution of approximately 0.06 cm(-1). Calculated spectra were matched to the observed spectra by nonlinear least squares regression over 100-cm(-1) intervals. More than forty parameters were estimated simultaneously, and the mean differences between the spectra were about one and a half times the mean noise in the experimental spectra.

However, the stretching absorptions for the C=O bond vary depending on the structure of carboxylic acids. The C=O bond of the free carboxylic acids shows a higher stretching frequency, 1760 cm−1, while H-bonded carboxylic acids (dimers) exhibit stretching absorptions at a lower frequency, 1710 cm−1. The C=O bond of the...
