Answer to Question #163887 in Physical Chemistry for Harsha

Question

Carbon monoxide shows an intense band at 2143cm^-1 reciprocate and a

weak absorption band at 4260cm^-1.Calculate the following

1.Fundamental frequency

2. Boltzmann constant and force constant

3.Anharmonicity constant

Answer 1

In order to determine experimentally the zero-point energy (ZPE=1/2∑hνi) and the value ZPE+H(T)−H(0) it is generally necessary to know all the frequencies of the normal vibration modes obtained by IR and Raman spectroscopy.

According to 'E= (1/2) mv2+ mgh' the body at motionless and at ground level has zero energy. It means the energy of a system is a relative term, which may be defined in terms of given state of the system. In thermodynamics the energy of the system depends upon absolute temperature (T) of the system.
