Absorption Coefficient of Quasi-Molecular Hydrogen.

Induced infrared absorption of molecular hydrogen in solid C

We report on the observation of induced infrared absorption in a molecular species trapped within a C60 lattice. Infrared spectra for interstitial H2 show distinct rotational and translational side-bands superimposed on the H2’s highly redshifted (54 cm ) fundamental vibrational mode. Data indicate that the hydrogen is rotating almost completely freely while at the same time undergoing localize...

Phycocyanin-specific absorption coefficient: Eliminating the effect of chlorophylls absorption

The applicability of algorithms for estimation of phycocyanin (PC) concentration based on light spectral reflectance heavily depends on the specific absorption of the pigment. But the determination of PC-specific absorption coefficient is not a straightforward task, as PC optical activity is overlapped by absorption of chlorophylls. The aim of our study was to determine a PC(625)—the specific a...

Regularity of the Interband Light Absorption Coefficient

In this paper we consider the Interband Light Absorption Coefficient (ILAC), in a symmetric form, in the case of random operators on the d-dimensional lattice. We show that the symmetrized version of ILAC is either continuous or has a component which has the same modulus of continuity as the density of states.

An alternative coefficient for sound absorption

The acoustic absorption coefficient is a number that indicates which fraction of the incident acoustic power impinging on a surface is being absorbed. The incident acoustic power is obtained by spatial integration of the incident intensity, which is (classically) defined as the time-averaged intensity associated with the incident sound field. The measurement of the effective, in situ, sound abs...
