The Stark and Zeeman effects in methyl silane

Microwave and sub-mmwave study of CH3SiH3 including the perturbation-allowed torsion–vibration difference band (ν12=0,ν6=3)↔(ν12=1,ν6=0)

“…where l 0 ¼ 0:7345600ð33Þ D [22] is the equilibrium dipole moment (except for a small correction). For a direct l-doubling transition, the corresponding expression is the same, except that the factor involving the product of two mixing coefficients is replaced by unity.…”

Anomalous transitions in two-level systems driven by the ac Stark effect

“…This D.C. assumption is equivalent to the combination of the rotating-wave approximation and the near-resonance approximation because, when n = 0, the value of ω is irrelevant (within very broad limits). Once the D.C. assumption is made, (14) becomes…”

“…1. Comparison between the numerical solution of (14) and the analytical solution given in the second equation of (17). The former was used to generate the open dots, while the latter was used to generate the line.…”

“…The accuracy of the analytical solution given in (17) is illustrated in Fig. 1 by making a comparison with the numerical solution of (14). To characterize the analytical solution for a 1 (t) 2 , the value of ( 0 /ω c ) was calculated with the second equation of (17).…”

“…The crossing field in this case is ξ C = 1.719 kV/cm. The diagonal electric dipole matrix element µ jj = µ(J, K, m J ) = µKm J /J (J + 1), where the permanent dipole moment µ = 0.734 560(3) D (1 D = 3.335 64 × 10 −30 C m) [14]. For this particular anticrossing, µ 22 = −µ 11 = µ/2.…”
