From the view of total energy and LUMO- HOMO energy gap, the most stable structure of C~6~0SiH~2 is C~2~v geometry in which bridging C(15)-C(30) bond length and bondorder are 0.1508nm and 0.9369, thus forming a cyclopropane-like structure. The electronic spectra and NMR spectra of...

are then compared. Through in-depth experimental analysis of product yields and timescales of formation at a peak laser intensity of 2.0 × 1014 W cm−2, we show that H3+yield decreases as the primary carbon chain length increases. Furthermore, we reveal additional formation mechanisms...
The eight-dimensional calculations showed that the CH stretching excitation does not have any important effect on the reaction and the seven-dimensional model with the CH bond length fixed works very well for the reaction. The excitation of H2 vibrations could enhance the reaction but is less ...
Along the further reaction pathway, the H–H bond length starts to decrease to a final equilibrium value of 0.75 Å. Figure 5 Calculated energy profile involved in the recombination of 2H on (a) S-corner and (b) Mo-corner of MoS2/Graphene nanocontact. The optimized structures of initial...
