We employ a pump-dump sequence of pulses with appropriate frequencies and time delays to achieve the selective breakage of a single bond by controlling the dissociation angle. The pump and dump pulse sequence exploits the unbound surface where dissociation occurs in a counterintuitive fashion; ...
The distorsion of the tetrahedra is discussed in terms of the interplay between bond angle relationships and the bond lengths. In the CH3 X structures in which C--X is a trigonal axis of symmetry, the tetrahedra are elongated along this axis. In other CH3 X structures, where two of the ...

Individual Ge-O bond lengths of 24 germanate tetrahedra in solid materials are observed to increase with decreasing 3, the average of the three O-Ge-O angles common to each bond, and with 1/cos(Ge-O-Ge). These correlations are examined in terms of valence electron population analyses obta...

Another feature of HB which adds to the complexity of its description is directionality; frequently, the angle A–H⋯B is not straight, meaning that the interaction is not purely electrostatic, and that a partial degree of covalency exists. This effect can be understood in terms of partial ...
Specifically, the addition of seven molecules shortens the B鈥揘 distance by 0.735 掳A in (HCN鈥揃F3)8 and 0.654A掳 in (CH3CN鈥#xD; BF3)8. Accompanying the large changes in B鈥揘 bond length are equally large changes in the N鈥揃鈥揊 angle....
The functional groups are also manifested in simple wettability tests (Fig. S1). HCP-CH3 floats on water and has a water contact angle of 107°. In contrast, HCP-OH is hydrophilic with a water contact angle of 33° and disperses homogeneously in water. Fig. 2c reveals the rough surface...
