An. Goncharov et al., DIRECT OBSERVATION OF THE 2ND-ORDER STARK-EFFECT OF THE X-B TRANSITION IN MOLECULAR-IODINE, Applied physics. B, Lasers and optics, 60(1), 1995, pp. 43-45
The second-order Stark shift of the components of the hyperfine struct
ure of the transition 1SIGMA(g)+ (upsilon'' = 0, j'' = 13, 15) --> 3Pi
(ou)+ (upsilon' = 43, j'' = 12, 16) of molecular iodine have been stud
ied by means of saturated absorption spectroscopy in an external cell
with the I2 vapour located in an electric field. The anisotropic polar
izabilities of the upper and lower levels together with the difference
between the isotropic polarizabilities of the levels of the transitio
n have been obtained.
