Calculate the force constant for the diatomic H35Cl given that the infrared spectrum exhibits a single line at 2886 cm-1

Calculate the percentage difference in the fundamental vibrational wavenumbers of 1H35Cl and 2H37Cl on the assumption that their force constants are the same.

Q2: what are the numbers of vibrational modes for Methane? and for N20?

The rigid rotor/particle-on-a-sphere can be used as a reasonable model for all of the following EXCEPT, and why. An electron in a hydrogen atom A hydrogen molecule rotation An electron confined on the surface of a spherical nanoparticle Predicting a rotational (microwave) absorption spectrum

Demonstrate that the probability of occupying a given vibrational energy level does not depend on whether one includes zero point energy (1/2hcv) or not..

3/ Please explain the answer in detail The force constant of 79B179B is 240 N/m. Calculate the fundamental vibrational frequency and the zero-point energy of 79Br79Br.

The "particle-in-a-box" problem consists of a particle of mass, m, contained within a one-dimensional well potential of length, L, for which the potential energy is zero for 0 < x< L, and infinite elsewhere. The allowed wavefunctions and energy levels of such a particle are given by the expressions: h? n?n? ; En 2 2/, sin (); L 2m L2
