State reconstruction of molecular spatial rotation

We establish a reconstruction approach for the rotational quantum state of linear molecules possessing a magnetic manifold. Our approximate method contains an iteration with generalized matrix inverses, processing the tomographic integral of the time-dependent molecular-axis distribution in a polar angle. As shown in a simulated example for an alignment state, the density matrix is determined in a high fidelity. An analytic tomographic formula is also derived for the symmetric top rotation. The state coherent in the quantum space of both the angular momentum and its magnetic projection can be approximately retrieved from the observable time-resolved solid-angle distribution of the molecular axis.

hERG channel is a target of drug cardiotoxicity evaluation and is closely associated with cell-cycle of some tumors, including gastric cancer, colon cancer, leukemia and glioblastoma.[1, 2] Therefore, a simple assay with high throughput, outstanding specificity and excellent sensitivity is urgent needed for understanding the roles of hERG channels in biological systems. Hence, we described a simple fluorescent probe CBH for imaging of hERG channels by employing a novel targeting group. The specificity of CBH was confirmed with electrophysiology, confocal imaging and immunofluorescence. Results showed that both solvatochromism and molecular rotation regulated the fluorescent emission of CBH and amplify the fluorescent signal, thus improving the sensitivity to hERG channels. Especially, it was proved the CBH probe has potential for quantitative analysis of the hERG channel expressed in tumor cells.[3]

Optimal approach to rotational state reconstruction of linear molecules

引用

Chinese Physics B 2011年第1期20卷 132-137页

作者：覃晓高军毅 Wuhan Institute of Physics and Mathematics Chinese Academy of Sciences Graduate University of the Chinese Academy of Sciences

We present a simulation for the reconstruction of the rotational quantum state of linear molecules to retrieve the density matrix. An optimal approach in the sense of minimal error limit is proposed, in which a variable set of angular frequency is properly chosen and the least square inversion is then applied. This approach of reconstruction from time-dependent molecular-axis angular distribution is proved adaptable for various object states, which has a good numerical stability independent of the selected rotational space.

The rotation and the phase transition in solid C60

引用

Chinese Journal of Chemistry 1996年第6期14卷 481-489页

作者： Xu, ZJ Yan, JM CHINESE ACAD SCI INST CHEMBEIJING 100080PEOPLES R CHINA

The interaction between C-60's in solid C-60 has been calculated by (exp-6-1) potential, and the cause and the controlled factor of the high rapid rotations of C-60's were discussed. In order to describe the disordered degree of C-60 rotation, an equivalent M is introduced. The phase transitions at the similar to 260 K and at the similar to 90 K are studied from the viewpoint of C-60 rotation. The potential barriers of the ordered rotation below the similar to 260 K and the disordered rotation above the similar to 260 K have been given, and the effect of the external pressure on the temperature of phase transition has also been given.
