The Q branch of the C-O stretching fundamental band of (CD3OH)-C-13 has been investigated. Starting from a high resolution (4 x 10(-3)cm-1) infrared Fourier transform spectrum and using a waveguide CO2 laser of 300 MHz tunability and an acoustooptic modulator for an extension of +/- 90 MHz, 31 new FIR laser lines have been observed. The related absorptions have been measured by means of optoacoustic detection. The frequency of one new FIR laser line was also measured. Eight tentative assignments are proposed for the IR absorption and FIR laser emissions.

Abstract
The Q branch of the C-O stretching fundamental band of (CD3OH)-C-13 has been investigated. Starting from a high resolution (4 x 10(-3)cm-1) infrared Fourier transform spectrum and using a waveguide CO2 laser of 300 MHz tunability and an acoustooptic modulator for an extension of +/- 90 MHz, 31 new FIR laser lines have been observed. The related absorptions have been measured by means of optoacoustic detection. The frequency of one new FIR laser line was also measured. Eight tentative assignments are proposed for the IR absorption and FIR laser emissions.File in questo prodotto:
