Quasi-classical trajectory (QCT) calculations are employed for the reaction F + HO(0,0)→HF + O based on the adiabatic potential energy surface (PES) of the ground 3A″triplet state. The average rotational alignment f...
In this paper, we report the first stereo-, regio-, and chemo-selective conversion of oridonin (1) from kamebakaurin (3). The overall yield in 7 steps is 9%.
This is a combined study of two different branches, photogrammetry and palynological morphology. The three-dimensional quantitative analysis of longan pollen grains by using SEM technique, electron computation techniq...
