LINESTRENGTH MEASUREMENTS FOR N2O AROUND 4-MU-M-PI[-SIGMA, PI[-PI, SIGMA[-PI, AND DELTA[-PI TRANSITIONS IN (N2O)-N-14-O-16 (2400-2850 CM(-1))

Linestrengths have been measured for five bands of (N2O)-N-14-O-16 using a Fourier transform spectrometer, with an effective response function width of about 5 X 10(-3) cm-1. The observed bands are the cold band nu2 + nu3, and the hot bands starting from the 01 10 level, associated to the nu1 + 2nu2, 2nu1, and nu2 + nu3 main bands. 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. An important contribution of the l-type resonance has been observed for both the 02(0)1 <-- 01 10 and the 02(2)1 <-- 01 10 transitions; the corresponding quadratic Herman-Wallis parameters have been calculated and compared to the observed ones.
