ANALYSIS OF HIGH-RESOLUTION MEASUREMENTS OF THE 2-NU(1)-NU(3) BAND OFOZONE - CORIOLIS INTERACTION WITH THE NU(1)+3-NU(2)+2-NU(3) BAND(3)

The 2v(1) + 3v(3) band of ozone, which occurs in the 5080 cm(-1) regio n, has been observed for the first time using a Fourier transform spec trometer, operating at 0.008 cm(-1) resolution and with a large pathle ngth x pressure product (3616 cm x 42.8 torr). Assignment of rotation- vibration transitions was done for J = 40 and K-a = 14. It was necessa ry to account for the Coriolis coupling between the levels of the (203 ) and (132) states to correctly reproduce the energy levels, particula rly for states with K-a = 4. In this way, we have obtained a very sati sfactory r.m.s. error of 1.8 x 10(-3) cm(-1), close to the experimenta l accuracy racy. In addition, line intensities of the 2v(1) + 3v(3) ba nd were measured and calculated, and transition moment constants deriv ed. Finally a complete list of line positions and intensities was calc ulated, leading to a total band intensity of S-V = 0.133 x 10(-21) cm( -1)/mole cm(-2) at 296 K. (C) 1998 Elsevier Science Ltd.
