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 specific rotational isomer of each isotopomer has been successfully done, providing isomer-specific…

Conformer specific nonadiabatic reaction dynamics in the photodissociation of partially deuterated thioanisoles (C6H5S-CH2D and C6H5S-CHD2).

The experimental finding that nonadiabatic transition dynamics are very sensitive to subtle changes in the nuclear configuration within the Franck-Condon region induced by the H/D substitution indicates that the S1/S2 conical intersection seam is quite narrowly defined in the multi-dimensional nuclear configurational space as far as the S-methyl predissociation reaction is concerned.

Conformer Specific Excited-State Structure of 3-Methylthioanisole.

Trans and cis conformers of 3-methylthioanisole have been spectroscopically investigated to reveal the conformer specific structural changes upon the S1 (ππ*) - S0 excitation, and it is found that the cis conformer undergoes the planar to pseudo-planar structural change upon theS1-S0 transition.

Structure and dynamic role of conical intersections in the πσ*-mediated photodissociation reactions

Conical intersection as a dynamic funnel in nonadiabatic transition dictates many important chemical reaction outputs such as reaction rates, yields, and energy disposals especially for chemical

Real-Time Observation of Nonadiabatic Bifurcation Dynamics at a Conical Intersection.

The time-resolved measurement of the product state distribution could separate two different dynamic channels unambiguously, unraveling the detailed dynamic mechanism of the nonadiabatic reaction taking place in the vicinity of the conical intersection.

It is shown that, in the ground state and in the first excited state of CH2DNH2 gas, there are well‐defined trans and gauche rotational isomers and that each of the gauche levels at n = 1 splits into two with a separation of about 2.8 cm−1 due to the resonance between the two equivalent gauche positions.
