Abstract

Effecitve dipole moment operator including higher order coriolis type electrodipole moments is developed for lower dyad states (v2,v4) of methane. Parameters in effective coriolis type dipole moments are calculated as for isolated v2 and v4 vibrational states as dyad (v2,v4) states. It is shown that coriolis type dipole moments for v1 and v3 states the same equation as for dyad (v1,v3) states. For the parameters in M₂₂(R) operator is obtained the value xxxxxxxxx (theor)=-2,2 10^-4D in agreement with experimental date of H. Sasada et al[12]:(Θ^x,y3_z)'=Θ^x,y3_z -3Θ^x,y_z ={(top line)-2,9x10^-9D(theor)[10,11] (bottom line) -4,4x10^-4D(exp)[12]
