New results are reported for the infrared optical parameters of Cd, Cu, Ga, Hf, Mg, Ni, Nb, Pd, white Sn, V, and W, at several temperatures. On the basis of the anomalous skin-effect theory, with diffuse scattering of electrons, electronic parameters are derived for wavelengths 10 and 15 µ, both for the metals examined by us, and, for Cu, Au, Pb, Ag, and white Sn, using results obtained elsewhere. These results are discussed on the basis of current models of photon-metal interaction and it is concluded that, for most metals, the wavelength dependence of the interaction frequency is not accounted for by these theories.

Kirillova and Charikov's own analysis yields results for τs and τp that do not fit their experiments if a self-consistent free-electron treatment is used and the behavior in the R'-X' plane predicted from their values of τs, τd and N. A frequency dependence of one of their τ's is still required to fit their results.
