| 摘 要： | 以皮秒Nd:YAG激光器的3倍频输出(355nm)泵浦光学参量产生/放大器(OPG/OPA),由其输出的514.5 nm的激光作为激发源,在室温下,对NO2分子在低气压情况下进行了激光诱导荧光研究.获得了在530～680 nm范围内的振动序列,将其归属为由第1电子激发态A2B2态向基电子态X2A1态不同振动态的跃迁,由此得到对称振动模式和角振动模式的谐振频率,分别为ω1=1 309.17 cm-1和ω2=747.05 cm-1.

| Abstract: | Laser induced dispersed fluorescence spectra (LIDFS) of NO_2 molecules, excited by the output of 514.5 nm of a pulsed Nd:YAG-pumped optical parameter generator and optical parameter amplifer (OPG/OPA), was obtained and analyzed at room temperature and at low NO_2 pressure. The vibronic progressions in the range of 530～680 nm obtained at low pressure was ascribed to the transitions from the first excited electronic state A~2B_2 to the vibrational levels of the ground electronic state X~2A_1. The harmonic frequencies of symmetric stretching and bending stretching was calculated: ω_1=1 309.17 cm~(-1) and ω_2=747.05 cm~(-1), respectively. |
