which can be contributed to Fermi resonance interaction between the C=O stretching mode and the COH bending mode.With the aid of the quantum chemistry calculations,it is concluded that there exists a fast vibrational population equilibrium process between the C=O and C=C stretching modes and the...
Before we play ball games or swim, it is better for us to do bending and stretching exercise first. This kind o f exercise is sometimes c 70warm-up(热身) exercise.Running is also a good exercise. I f we cannot run q 71 , we can jog. Jogging means running not very quickly. Again...

At least five distinct C-O stretching bands are observed sequentially between 2025 cm 1 and 2097 cm 1 as a function of exposure. Furthermore, in contrast to previous studies, LEED results suggest that the (5×1) reconstruction is not fully lifted, even after exposure to relatively high CO ...

The very small Raman shift corresponding to the C–C stretching vibration as well as the greatest d1 value accurately determined by X-ray analysis revealed that 10c has a very weak C–C bond. Nonetheless, 10c and other dispiro(dibenzocycloheptatriene)s are thermodynamically and kinetically stable...
