本工作观测了双光子能量在35180-36002cm^-^1范围内吡啶分子的共振多光子电离谱。对电子跃迁S~1(^1B~1)→S~0(^1A~l)的振动带做了归属, 首次在^1B~1态观察到7个新的振动模。讨论了N原子取代对分子结构及振动模的影响。

Resonant multiphoton ionization spectra of pyridine vapor in the two-photon energy region of 35180-36002cm^-^1 has been observed. The vibrational bands observed in the S~1(^1B~1)→S~0(^1A~1) transition are assigned. Seven new vibrational bands are observed in ^1B~1 state for the first time. The effects of N substitution on the molecular structure and the vibrational modes are also discussed.
