Photoacoustic Detection of New Bands of HCN between 11 390 and 13 020 cm(-1).
A laser photoacoustic technique has been used to measure the absorption spectrum of HCN in the region from 11 390 to 13 020 cm(-1) with a resolution that is limited by the Doppler- and pressure-broadened linewidth. This is a very sensitive technique that has allowed us to measure very weak bands with a small volume of gas. These measurements provide the rovibrational constants for a number of newly observed vibrational energy levels. Copyright 2000 Academic Press.
