FIRST STUDY OF THE UPSILON(2)=3 DYAD((130),(031)) OF OZONE THROUGH THE ANALYSIS OF HOT BANDS IN THE 2300-2800 CM(-1) REGION

Hot bands v(1) + 3v(2) - v(2) and 3v(2) + v(3) - v(2) of O-16(3) in th e region 2300 - 2600 cm-(1) and the cold band 3v(2) + v(3) in the regi on 3050 - 3110 cm(-1), corresponding to the v(2) = 3 dyad {(130), (031 )}, have been observed for the first time, using the Fourier Transform Spectrometer (FTS) at Reims and the usual experimental setup providin g a large product pressure x path length, p x l. Three hundred sixty-f ive rovibration energy levels of the upper states were obtained with J and K-a up to 46 and 9, respectively. The fit of these data gives a r .m.s. deviation of 1.93 x 10(-3) cm(-1). The v(2) dependence of the ro tational parameters A, B, and C for the (1v(2)0) and (0v(2)1) states i s discussed.
