Abstract

Foreign-gas broadening and shift have been measured for transitions in the ν2, 2ν2 and ν4 bands of ammonia using a diode laser spectrophotometer. The measurements were performed by using foreign-gases such as CO2, N2, air, H2, and He at room temperature. The pressure-broadening and shift coefficients may be useful in modelling planetary atmospheres and the recently developed infrared (i.r.) ammonia laser. The experimental results are compared with the Anderson-Tsao-Curnutte theory for broadening CO2 and N2, which have large quadrupole moments. The agreement is satisfactory on the average. © 1990.
