Gas-phase fundamental and CH and CO overtone spectra (700-17 500 cm -I) of 2,2,2trideuteroacetaldehyde were recorded using FTIR and laser photoacoustic techniques. The Fermi resonance structure in the overtone spectra of the coupled CH stretching and in-plane CH bending vibrations is analyzed with a tridiagonal Hamiltonian, yielding a large effective coupling constant, I k ;bb I = 93 cm I, corr...

The century-old controversy over two contradicting theories on radiation pressure of light proposed by Abraham and Minkowski can come to an end if there is a direct method to measure the surface deformation of the target material due to momentum transfer of photons. Here we have investigated the effect of radiation pressure on the surface morphology of Graphene Oxide (GO) film, experienced due ...

Microfibers composed of azobenzene-based photochromic amorphous molecular materials, namely low molecular-mass photochromic materials with a glass-forming property, could be fabricated. These fibers were found to exhibit mechanical bending motion upon irradiation with a laser beam. In addition, the bending direction could be controlled by altering the polarization direction of the irradiated li...

Observations of the self-deflection effect for an asymmetrical continuous-wave laser beam in sodium vapor are described, and comparisons based on theoretical calculations are made. A self-bending angle as large as eight diffraction widths was recorded, and strong attenuation of the on-axis radiation due to self-bending was measured. At -200'C the self-deflection angle increased linearly with be...

In the present paper, the different techniques used for the determination of changes of surface stress of solid electrodes, as well as the kind and quality of information that can be achieved using these methods are discussed. The most important methods are briefly reviewed and advantages/drawbacks highlighted. Special attention is paid to issues related to the use of the “bending beam” (“bendi...
