Abstract :
Fourier-transform intra-cavity laser absorption spectroscopy has been used to record high-resolution vibration–rotation overtone spectra of carbon-13 substituted acetylenes, H12C13CH and H13C13CH, in the third CH stretching overtone region between 12 500 and 12 730 cm−1. The observed spectra of both species contain only parallel bands for which rovibrational spectroscopic parameters have been determined. Several anharmonic resonances have been identified and rotationally analysed using traditional vibration–rotation theory. Altogether six bands, which include ν1 + 3ν3 and 4ν3 for H12C13CH and ν1 + 3ν3 for H13C13CH, have been observed for both species. Four of the six bands in each molecule are reported for the first time.
