Peptide Bond Vibrational Coupling
The Journal of Physical Chemistry B, 2007Neutral trialanine (Ala3), which is geometrically constrained to have its peptide bond at Phi and Psi angles of alpha-helix and PPII-like conformers, are studied at the B3LYP/6-31+G(d,p) level of theory to examine vibrational interactions between adjacent peptide units.

Vibrational coupled cluster theory
The Journal of Chemical Physics, 2004The theory and first implementation of a vibrational coupled cluster (VCC) method for calculations of the vibrational structure of molecules is presented. Different methods for introducing approximate VCC methods are discussed including truncation according to a maximum number of simultaneous mode excitations as well as an interaction space order ...

Coupled Vibration of Embedded Foundation
Journal of Geotechnical Engineering, 1989The paper describes a simplified mathematical model of the coupled horizontal and rocking vibration of an embedded foundation. Vibration tests of the foundation with different embedments were conducted and compared with different methods. Conclusions drawn from the theoretical analysis and dynamic experiments are presented.

Torsional Vibration and Related Coupled Vibration
2019Torsional vibrations are often problematic in transient responses when a rotor-bearing system starts up. The vibration is more predominant and unavoidable in geared rotor systems. Though torsional vibration poses long-term problems, new methods of rotor design have been established by employing the transfer matrix method, which are capable of ...

Vibrational-vibrational coupling in air at low humidities
The Journal of the Acoustical Society of America, 1986Calculations of sound absorption in air are traditionally based on the assumption that molecular relaxations in nitrogen and oxygen are independent. In binary mixtures of these two gases, however, molecular relaxation is known to be controlled by a very strong vibrational-vibrational (V-V) coupling, which influences both the relaxation times and the ...

1991
In Chapter 1, we considered the free vibrations of a two-mass system with three springs of equal stiffness; we found that there were two normal modes of vibration. Such a system could have been viewed as consisting of two separate mass/spring vibrators coupled together by the center spring (see Fig. 1.20).

Vibration-vibration coupling in the dissociation of a diatomic gas
Journal of the American Chemical Society, 1970Abstract : A previous formulation of the master equation for the dissociation of a dilute diatomic gas is extended to the nondilute case by the inclusion of V-V transitions. Using existing experimental and theoretical data for other molecules, estimates are made for the V-V transition probabilities in H2.
