1-Phenyl-3H-2,3-benzodiazepin-4(5H)-one
The seven-membered ring in the title compound, C(15)H(12)N(2)O, adopts a boat-shaped conformation (with the methyl-ene C atom as the prow and the double-bond C=N pair of atoms as the stern). In the crystal, adjacent mol-ecules are linked by an N-H⋯O hydrogen bond to generate helical chains running along the a axis of the ortho-rhom-bic unit cell.

The seven-membered ring in the title compound, C(13)H(16)N(2)O(2), adopts a boat-shaped conformation (with the C atoms of the fused-ring as the stern and the C atom bearing two methyl groups) as the prow.
متن کاملProperties of the Neutron
In this lecture, we present a brief description of properties of the neutron. We describe its internal properties: life time, mass, charge, magnetic and electric dipole moments... Particular attention will be paid to two most important characteristics of the neutron – its life time and electric dipole moment – both of them are now studied in a few different experiments. Moreover, the measuremen...
متن کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولNeutron–3H and Proton–3He Zero Energy Scattering
The Kohn variational principle and the (correlated) Hyperspherical Harmonics technique are applied to study the n − 3H and p − 3He scattering at zero energy. Predictions for the singlet and triplet scattering lengths are obtained for non–relativistic nuclear Hamiltonians including two– and three– body potentials. The calculated n−3H total cross section agrees well with the measured value, while...
