Abstract
N2, Air, O2, H2, Ar, and He broadening and shift of the aQ(9,)) transition line of ammonia have been measured in the temperature range 180-380 K with errors of ~2 and 10% respectively. All the measurements have been fitted with the well-known power low, which holds very well in the temperature range considered here. N2 pressure effects have also been compared with calculations based on the Anderson-Tsao-Cornutte (ATC) theory with mixed results, anyway much more satisfactory for broadenings than shifts.File in questo prodotto:
