Emission spectra of HCN/HNC in the 2-5 microm range of astrophysical interest.
Emission from H12C14N observed with a Fourier transform spectrometer from a radio-frequency excited plasma is reported in the 2400-3400 cm(-1) spectral range of astrophysical interest. The molecular constants, for 21 vibration-rotation bands are given, as well as estimates of the first-order Herman-Wallis coefficients for 11 bands. These constants are derived from about 900 observed transitions in HCN, and are used to generate a sequential linelist of about 1400 calculated line positions, within a standard deviation equal to 3 x 10(-4) cm(-1). The relative intensities of the observed lines are also reported, as well as those for the nu1 band of H14N12C, at 3650 cm(-1), simultaneously observed from the same plasma.
