Table 2 Ground-State Polarizability (ai) and Trace of the Tensor of Polarizability Variation (l/3)Tr[Aa] for Several Optical Dyes and Charge Transfer Complexes...

A number of usually small terms related to the ground-state polarizability, the transition polarizability and the square of the dipole difference have been neglected in (120) and (121). Complete expressions have been given (Liptay, 1974 Wortmann et ai, 1992). Neglecting changes of the polarizability upon excitation, the effective dipole difference in solution in (120), (121) is given by (122). 

Intensity arises from the dependence of the ground-state polarizability on molecular vibrations only... 

Ground-state polarizability and its dependence on molecular vibrations is enhanced via electronic transition(s)... 

The quantum mechanical expresrion for the ground-state polarizability, valid except in regions of electronic transition. 

For the pyrimidine molecule we also calculated the frequency dependence of the Sj state polarizability up to the first resonance. The change of the dynamic polarizability upon excitation is displayed in Fig. 1, for the a, a, and components, respectively. The dispersion of the ground state polarizabilities in the same frequency interval as for the excited state does not differ significantly from... 

Maroulis et al.122 have applied their static polarizability, finite field technique to a study of the 22 electron diatomics CP , BC1, CC1+ and PO+. The vibrational contribution to the ground state polarizability has also been calculated. The dipole polarizability and other properties of YbF have been investigate in the unrestricted Dirac-Fock approximation by Parpia123 and the static second hyperpolarizability of the Cu2 dimer has been calculated in a correlation corrected UHF study by Shigemoto et al.124... 

Polarizabdities are no-mally expressed in cgs units of cm. Ground state polarizabilities are in the range of 10- cm = 1 and hence are often... 

The ground-state polarizabilities of the tetravalent actinide ions Th , Pa, and U have been computed at different relativistic levels using the... 

Data for d"s states, see original paper [6]. — For further excited states, see original paper [5]. —Reported as ground state polarizabilities in a 1971 table [7] and converted to SI units in [8].
