International audience; By using depopulation laser techniques, like IR-UV population labeling coupled to mass-selected R2PI detection, we confirm that four tautomers are responsible for the near UV spectroscopy (310-280 nm) of guanine: two enol and

The time evolution of the first excited states of ethylene, and alkyl substituted ethylenes, isomers with formula C6H12, has been studied by the femtosecond pump probe method, using mass spectrometric detection, in the region of 6 eV (200 nm). Two cy

Four new hot bands of HNSi, 2ν1−ν1, ν1+ν3−ν3, 2ν1+ν3−(ν1+ν3), and ν1+ν2−ν2, are observed in emission from a radio frequency excited plasma with a high resolution Fourier transform interferometer. The equilibrium rotational and vib

Radiationless deactivation pathways of excited gas phase nucleobases were investigated using mass-selected femtosecond resolved pump-probe resonant ionization. By comparison between nucleobases and methylated species, in which tautomerism cannot occu

The emission spectrum of ZrCl has been observed in the 1800-12 000 cm(-1) region using a Fourier transform spectrometer. The molecules were excited in a microwave discharge of a mixture of helium and a trace of ZrCl(4) vapor. In addition to the C(4)D
