The No Vibrational Fundamental Band: Temperature Dependence of N2- Broadening Coefficients

Rovibrational spectra of the vibrational fundamental of nitric oxide have been recorded under N2-broadening conditions using the Solar McMath FTS at the Kitt Peak National Observatory. The temperature range for the experiments was 296K to 183K. Qualitative as well as quantitative discrepancies are observed between these experimental determinations of the temperature dependence.
