Pyrolysis of CH3 N3 under the protection of NO generates a continuous methylnitrene CH3 N diradical beam that enables the ionization energies of different ionic states of the CH3 N diradical to be determined by HeI photoelectron spectroscopy (PES; see spectrum) and both ab initio and density functional theory (DFT) calculations. The ab initio and DFT(More)
A hydrokinetically simulated sucking was made to study the self-intermittent vacuum drainage of the root canal.Results showed that due to the shape difference between diameters at the upper and lower parts of the canal,the high-speed air-flow at the lower-end opening can drain the fluid below the opening out while the lower-speed air-flow at the upper(More)
