At each fixed distance, the potential energy was calculated, and optimized geometry was used to obtain the rotational constants and a vibrational analysis was used to obtain the vibrational frequencies of the orthogonal degrees of freedom, after projecting out the reaction coordinate. The zero-point ...

X-ray molecular structure of 4 with thermal ellipsoids at 50% probability level. The C6H5 groups at the P atom and the C6H4 and CH2 H atoms are omitted for clarity. Full size image As shown in Fig. 4, the four complexes that contain two inequivalent N,P-ligands at the ruthenium cent...
The results of molecular beam Fourier transform microwave (FTMW) investigations of the van der Waals complexes of difluoromethane with 1,1-difluoroethene (DFE) and trifluoroethene (TFE) are reported. The rotational parameters of the complexes have been interpreted in terms of a Cs geometry with...
The compounds exhibit fac -[Re(CO) 3 N 3 ] or fac -[Re(CO) 3 N 2 O] coordination geometry in the cationic molecular units. Both compounds are chemically robust and survive histidine and cysteine challenges with greater than 95% recovery. Crystal data for C 21 H 23 BrFN 4 O 3 Re ...
Wild type CH2 domain molecules are small in size, usually less than 15 kD. Engineered CH2 domain molecules can vary in size and may have a molecular weight up to 22 kDa. In some embodiments, engineered CH2 domain molecules substantially retain the same loop regions of a wild type CH2 domain...
