Molecules of the title compound, C16H14N2O, a potential plant‐growth regulator, are linked into chains by intermolecular C=O...H—N hydrogen bonds. These chains are weakly interconnected by π–π stacking interactions to form a three‐dimensional framework. A comparison of the geometric parameters of the title molecule and several related benzimidazoles and pyrrolidones is presented.<!?tpb=22pt> 相似文献

A new concept of a free space, high-speed (Gbps) optical communication system based on spectral encoding of radiation from a broadband pulsed laser is developed. It is shown that, in combination with the use of partially coherent laser beams and a relatively slow photosensor, scintillations can be suppressed by orders of magnitude for distances of more than 10 km. 相似文献

Uncatalyzed cycloaddition of 3,4‐dihydroisoquinolines to (E)‐1,1,1‐trifluoro‐3‐nitro‐2‐butene via Grob reaction provide a simple one‐step route to the 5,6‐dihydropyrrolo[2,1‐a]isoquinolines, which represent the basic structural framework of the antitumor active alkaloid crispine. 相似文献

A simple and effective self-consistent scheme is proposed for the determination of the average potentials which allows thermodynamic functions and other characteristics of lattice systems in equilibrium to be calculated with high accuracy and short computing time. This scheme has been used for analysis of the expressions for the coefficients of diffusion and electrical conductivity obtained on the basis of the modern statistical theory of nonequilibrium processes. Results of the simulations are correlated with the data of Monte Carlo simulations obtained using parallel vector algorithms on a Cray TZE computer of the Max Plank Society (Germany). 相似文献

We apply the self-consistent diagram approximation to calculate equilibrium properties of lattice systems. The free energy
of the system is represented by a diagram expansion in Mayer-like functions with averaging over states of a reference system.
The latter is defined by one-particle mean potentials, which are calculated using the variational condition formulated. As
an example, numerical computations for a two-dimensional lattice gas on a square lattice with attractive interaction between
nearest neighbours were carried out. The critical temperature, the phase coexistence curve, the chemical potential and particle
and vacancy distribution functions coincide within a few per cent with exact or with Monte Carlo data.
