Spectroscopic ellipsometry measurements with the Grating Division-of-Amplitude Photopolarimeter

SPIE Proceedings, 2002
The Grating Division-of-Amplitude Photopolarimeter (G-DOAP) obtains very rapid measurements of the complete polarization state of light over the spectral bandwidth of the instrument. Application to polarimetry, ellipsometry, and Mueller matrix ellipsometry is discussed.

Mean amplitudes of vibration for cyclohexene from spectroscopic data

Monatshefte f�r Chemie, 1974
A normal coordinate analysis is performed for cyclohexene (C6H10). The calculated frequencies for C6H10 and C6D10 are reported. The mean amplitudes of vibration for all types of interatomic distances in these two molecules were also computed. Those of the bonded distances and nonbonded C−C distances in C6H10 are compared with the corresponding data ...

Spectroscopic Ellipsometry Using the Grating Division-of-Amplitude Photopolarimeter (G-DOAP)

Thin Solid Films, 2004
Abstract Spectroscopic ellipsometric (SE) measurements obtained using the grating division-of-amplitude photopolarimeter (G-DOAP) are presented. G-DOAP measures all four Stokes parameters of arbitrarily polarized light over the full spectrum (550–940 nm in the present case), with no moving parts or modulators in less than 1 s.

Spectroscopic Amplitudes and Microscopic Substructure Effects in Nucleon Capture Reactions [PDF]

Physical Review C, 2001
Spectroscopic amplitudes play an important role in nuclear capture reactions. These amplitudes are shown to include both single-particle and polarization effects: the former through their spatial dependence and the latter through their normalization (the spectroscopic factors).

Determination of phase and amplitude of degree of coherence from spectroscopic measurements

Optics Communications, 2000
In a recent study, James and Wolf [D.F.V. James, E. Wolf, Opt. Commun. 145 (1998) 1] have shown theoretically that if spectral measurements are made at several off-axes points in Young's interference experiment, the amplitude and the phase of the spectral degree of coherence can be determined.

Alpha Particle Spectroscopic Amplitudes in the j-j Coupled Shell Model

Nuclear Physics A, 1974
Abstract Formulae for calculating spectroscopic amplitudes for α-transfer reactions are developed in the framework of the j - j coupled harmonic oscillator shell model. It is shown that the amplitudes can be written as a sum of coupled two-neutron and two-proton spectroscopic amplitudes, illustrating that many properties of α-transfer reactions can

Mean amplitudes of vibration for CH3SO2F and CH3SO2Cl from spectroscopic data

Journal of Molecular Structure, 1973
Abstract A tentative assignment of vibrational frequencies for CH 3 SO 2 F and CH 3 SO 2 Cl is established. The available spectral data from literature were supplemented by new infrared measurements in the liquid phase. A normal coordinate analysis was performed on the basis of the assigned frequencies.

Spectroscopic imaging by dephasing amplitude changing (SIDAC).

Radiation medicine, 1989
A technique for spectroscopic imaging based on a new concept of dual encoding (i.e., both phase and frequency encoding) of position along the direction of the read-out gradient is proposed. The phase encoding is produced by changing the amplitude of the dephasing gradient as in conventional phase encoding.

The Distributions of Periods and Amplitudes of Late-Type Spectroscopic Binaries

1985
Photoelectric radial-velocity measurements, made on an unhurried observing schedule, have permitted the discovery of groups of spectroscopic binaries in which the usual observational discrimination against long periods and small amplitudes is much reduced.
