| 英文摘要 | The Rydberg-state decay dynamics of carbon disulfide (CS2) has been investigated by (2+1') resonance-enhanced multiphoton ionization with the pump-probe technique (pump wavelength 266 nm and probe wavelength 400 nm) on our homebuilt femtosecond laser system. The CS2 is pumped into Rydberg state 6ssigma(g) by two 266-nm photons, corresponding to the excitation energy 9.4 eV, and then ionized by temporally delayed 400-nm pulse. The CS2 ion yield dependence on the time delay determines the excited-state lifetime to be 409 +/- 6 fS for (CSS)-S-32-S-32 and 441 +/- 7 fs for (CSS)-S-32-S-34, respectively, at 265 nm pump and the isotopically averaged lifetime 1034 +/- 31 fs at 267.5 nm pump. The wavelength dependence of the lifetime may be due to the effect of electron spin on the potential energy surface-namely, separately subjected to two different mechanisms: internal conversion and intersystem crossing interaction. |
