Tanisha Billups 4/7/10 HOMEWORK I-10 9.17b  A point mass rotates in a circle with  l  = 2, Calculate the magnitude of its angular momentum and the  possible projections of the angular momentum on an arbitrary axis. 9.18b  Draw the vector diagram for all the permitted states of a particle with  l  = 6. 9.2  The mass to use in the expression for the vibrational frequency of a diatomic molecule is the effective mass  μ  =  m A m B /(m A  + m B ),where m A  and m B  are the masses of the individual atoms. The following data on the  infrared absorption wavenumbers (in cm –1 ) of molecules are taken from  Spectra of diatomic molecules , G.  Herzberg, van Nostrand (1950): Calculate the force constants of the bonds and arrange them in order of increasing stiffness. 9.4  Calculate the energies of the first four rotational levels of  1 H 127 I free to rotate in three dimensions, using for  its moment of inertia  I  =  μ R 2 , with  μ  =  m H m I /(m H  + m I ) and
