✦ Synopsis

The vibration-rotation energy levels of the (131) state of ozone have been obtained, covering the whole range of J up to 33 and K a up to 9, from the analysis of the hot band, observed for the first time n 1 / 3n 2 / n 3 0 n 2 in the 3400 cm 01 region. The assignments have been confirmed by the analysis of the cold band n 1 / 3n 2 / n 3 recorded in the 4100 cm 01 region. This enabled us also to derive the transition moment w 000 -131 z Å 1.8 1 10 04 D. The analysis has been performed using single state Watson's Hamiltonian where the 164 levels are fitted with 10 parameters with a r.m.s. deviation of 1.9 1 10 03 cm 01 , near the experimental accuracy. Note that the analysis involving simultaneously three interacting states of the Triad {( 230), ( 131), (032)} has also been performed which however did not result in an improvement of the r.m.s. deviation of the fit. This work allows us to observe a quasilinear variation of A(1£ 2 1), B(1£ 2 1) / C(1£ 2 1) and D K (1£ 2 1) with respect to £ 2 . This result is of first importance to derive band centers of perturbing levels involving £ 2 § 3.
