NO2 jet cooled visible excitation spectrum: Vibronic chaos induced by the X̃ 2A1–Ã 2B2 interaction

摘要: Significant improvements have been obtained on measurements of the NO2 jet cooled excitation spectrum in 16 300–18 502 cm−1 range, previously by Smalley et al. [J. Chem. Phys. 63, 4977 (1975)], Persch [Ber. Bunsenges. 92, 312 (1988)], and Hiraoka Mol. Spectrosc. 126, 427 (1987)]. The concern first rotational analysis, owing to a better resolution (150 MHz) absolute precision (500 MHz), second completeness purity resulting vibronic sequence, sensitivity. As result, 159 energy levels observed 16 500–18 500 where 210±10 are expected. A detailed comparison with previous results is presented. statistical analysis corresponding spacings shows that long range correlations up 50 mean present, confirming chaotic behavior this set levels. Furthermore, we analyze rovibronic interactions (or rotation...
