Liquid methanol at densities up to rhorho(0) = 1.7 was studied by NMR in a specially designed diamond-anvil cell. Methyl and hydroxyl resonances have been separately observed at pressures to 43 kbars which exceeds equilibrium freezing pressure of methanol. The chemical shift difference between methyl and hydroxyl protons increases nonlinearly with increasing density, indicating a noticeable dec...

The many-body Gaussian core model involves a potential energy function that consists of a sum of repelling pair interactions, each of which is a simple Gaussian function of distance. This paper examines the linear elastic response of the model for its stable lattices at absolute zero temperature, in D=1, 2, and 3 dimensions. Owing to the fact that the Gaussian function is self-similar under Fou...

An absorbing substrate of complex refractive index n(2)-jk(2) can be coated by a transparent thin film of refractive index n(1) and normalized thickness zeta so that the ratio of complex reflection coefficients for the p and s polarizations of the film-covered substrate rho is the inverse of that of the film-free substrate rho at a given angle of incidence phi. A pair of parallel (metallic) mir...
