LINESTRENGTH MEASUREMENTS FOR N2O AROUND 4-MU-M-SIGMA[-SIGMA TRANSITIONS IN 4 ISOTOPIC-SPECIES (2400-2600 CM-1)

Linestrengths have been measured for 12 bands of N2O using a Fourier transform spectrometer, with an effective response function width of about 5 X 10(-3) cm-1. The observed bands for (N2O)-N-14-O-16 are the cold bands nu1 + 2nu2 and 2nu1 and their associated hot bands starting from the 02(0)0 or 10(0)0 levels. Transitions starting from the 00(0)0 level have also been measured for the minor isotopic species (N2O)-N-14-O-18 (NNO)-N-15-N-14-O-16, and (NNO)-N-14-N-15-O-16. Measurements have been carried out with a relative accuracy better than 2%. Analysis of the results yields the squared vibrational transition dipole moment and the parameters describing the vibration-rotation interaction effects. (C) 1994 Academic Press, Inc.
