One‐ and two‐photon‐resonant multiphoton ionization spectra of CS2 from 45 500 to 48 100 cm−1

摘要: One‐ and two‐photon‐resonant multiphoton ionization spectra of the low energy region intense 1 B2 state room temperature CS2 are reported. A comparison these with one another, as well absorption spectra, yields a frequency 46 247 cm−1 for electronic origin transition. Most features in this can be assigned transitions to excited bending levels. The mode is found 429 cm−1, excellent agreement results from higher spectrum. Two‐photon excitation used observe, first time, antisymmetric stretch mode. Its 1567 close corresponding ground value.
