Abstract
A method, called the procedure of supercombination differences, has be en developed in order to determine the a(1)-a(2) (K = 3) ground state splittings for symmetric top molecules from infrared spectra. By formi ng normal combination differences corresponding to both the components and then their differences the splittings were evaluated for the CHD3 molecule up to J = 20 with the aid of 11 rotation-vibration bands. By applying the theoretical J dependence of the splittings they could be well explained with one parameter 2h(3) = 2.2960(90) x 10(-10) cm(-1) .
