| Abstract: | The resonance-enhanced multiphoton ionization (REMPI) spectrum of 2 butanone in 467～488nm was obtained using multiphoton ionization-time-of-flight mass spectrometric technique and dye laser. By analyzing the spectrum, we have ascertained that the strongest peak in the REMPI spectrum,62305cm-1,could be attributed to one component of the 3d Rydberg transition, the peaks in 63291～63898cm-1 are mixed Rydberg valence vibronic transitions, and 63291cm-1 is the 0-0 transition of the state. |
