Rotational spectroscopic study of S-methyl thioformate

ROTATIONAL SPECTROSCOPIC STUDY OF SOLVATION OF HCCCN BY He-ATOMS

Spectroscopic separation of the methyl internal-rotational isomers of thioanisole isotopomers (C6H5S-CH2D and C6H5S-CHD2).

Two distinct rotational isomers of thioanisole-d1 (C6H5S-CH2D) and thioanisole-d2 (C6H5S-CHD2) with respect to the internal rotation of the methyl moiety have been identified and characterized spectroscopically using the resonantly enhanced two photon ionization, UV-UV hole burning, and slow-electron velocity map imaging techniques. From the statistical weights, the definite assignment for the ...

Spectroscopic rotational velocities of brown dwarfs

We have obtained projected rotation velocities (vrot sin i) of a sample of 19 ultracool dwarfs with spectral types in the interval M6.5–T8 using high-resolution, near-infrared spectra obtained with NIRSPEC and the Keck II telescope. Among our targets there are two young brown dwarfs, two likely field stars, and fifteen likely brown dwarfs (30–72MJup) of the solar neighborhood. Our results indic...

The Rotational Spectrum of Tunnelling Methyl Groups

The quantum-classical transition of methyl rotation highlights conflicting assumptions of quan­ tum and classical mechanics, the first assuming that identical fermions are indistinguishable while the second recognises they are distinguishable through their histories. When this is introduced into quantum mechanics, the two are compatible and there is a smooth transition of the methyl rotational ...
