The Longuet Higgins recurrence relations of the dynamical J-T problem are equivalent to a system of two ordinary linear first order differential equations whose solutions are required to belong to the space of entire functions. This requirement deter

It is conjectured that the component wavefunctions of the E⊗ϵ Jahn-Teller Hamiltonian are terminating series of generalized spheroidal wavefunctions. Numerical calculations strongly support the conjecture. The solution of the Rabi Hamiltonian is a

A fit of the reflectivity data of KCP is given using the expressions of the small polaron theory. It is further shown that small polaron theory gives the same optical properties as either a two site model with a deformation coordinate and Franck Cond

An analysis of photoinduced dichroism and torque data in YIG (Si) is made in terms of a small polaron model. Good agreement between theory and experiment is found for the frequency — and angular dependence of the effects if the distortions of the l

Experimental data for the absorption coefficient of p-type LaCoO 3 at T = 293° K and T = 4.2° K are presented. At low temperatures considerable phonon structure is seen in the absorption. A theoretical explanation of the frequency dependence of the

The reversible photomagnetic effects are described as polaronic charge transfer between different octahedral sites via the intermediary of tetrahedral sites. The rate equations are given and the stationary distribution is derived together with expres

The mobility of small polarons is calculated as function of the temperature and the frequency. The frequency dependence is similar to the frequency dependence in the case of free electrons. For fixed frequencies the mobility increases strongly with t

Reflectivity measurements of semiconducting BaTiO 3 samples of varying electrical conductivity cannot be explained by Drude's free charge carrier theory but by theory of the optical properties of the small polaron.

Expressions are given for the frequency dependence of the optical absorption and for the d.c. differential conductivity of small polarons in the presence of a high d.c. electric field. The experimental consequences of the results are discussed with s
