The direct Itype transitions of H l 3 C , 4 N l 6 0 in the vibrational states ( i^ i ' s ) = (01) and (03) were measured in the frequency range from 18 to 40 GHz. These transitions show a nuclear quadrupole hyperfine structure caused by the l 4 N nucleus, which could partially be resolved at Doppler-limited resolution. The analogous transitions of the parent species. H l 2 C l 4 N 1 6 0 , were ...

The effect of illumination on the surface interaction and the reaction between NO ? C2H5OH was investigated on TiO2 and Ag/TiO2. By means of Fourier transform infrared spectroscopy the formation of an absorption band at 2,210 cm was observed on pure TiO2, which was attributed to the NCO species. Similar measurements on Ag/TiO2 produced another spectral feature at 2,170 cm, which was assigned to...

In a recent work (Shao et al., 2009), a nonconsensus opinion (NCO) model was proposed, where two opinions can stably coexist by forming clusters of agents holding the same opinion. The NCO model on lattices and several complex networks displays a phase transition behavior, which is characterized by a large spanning cluster of nodes holding the same opinion appears when the initial fraction of n...

We report the first measurement of the vibrationaland rotational-state distributions in the NCO fragment resulting from photolysis of HNCO. Recent studies have drawn conclusions about the photochemistry of HNCO and the vibrational distribution in the NCO fragment from observations of the kinetic energy distribution of the H atom produced in this photolysis; however, there has been no direct obs...

When a function’s value is known at several distinct points, there exist “numerical differentiation” formulas which provide estimates for the first derivative, and with various error bounds. In fact, many times the numerical differentiation formula chosen must be complex to avoid intolerable error as shown below. However, in computer simulations, as well as in real-time programming, while sever...
