Ab initio calculations using the B3LYP and CCSD(T) methods were employed in this work to explore the most stable structure of the intriguing compound Be(BH₄)₂, for which as many as seven different structures have been proposed in the literature. Use of the B3LYP density functional method with several large basis...
A Graphic User Interface is developed to determine the existence of a
particular sequence of piano notes within a monophonic sound waveform.
Such waveforms are recorded within the Graphic User Interface and then
passed to the monophonic analysis engine. The first phase of analysis segments
the PCM sound data to...
There is a new possibility of generating deep ultraviolet laser radiation from a solid-state source. With recent advances in material development, a new nonlinear optical crystal provides a greater damage threshold than current materials making higher conversion efficiencies possible.
This thesis examines the possibility of using this crystal to generate...
The development and applications of a 0.2 cm⁻¹ resolution
Nd-YAG laser powered coherent anti-Stokes Raman
spectroscopy, CARS, spectrometer for gas phase studies is
chronicled in this thesis. Applications including CARS
lineshape analysis, resonant CARS, and CARS of transient
species and excited state molecules is reported.
The intensity of the signal...
A variety of laser spectroscopic methods are employed in this
thesis research for studies of CF₃NO, an interesting model
photodissociative system, and for investigation of low energy rotations
and vibrations of small molecules and low molecular weight clusters in
free jet expansions.
Nonradiative energy decay for electronically excited CF₃NO is...
Mobile and telecommunication industry has experienced tremendous growth in the recent past. Miniaturization and increased functionality have become necessary for all passive components in the system. Bandpass filters are critical passive components in any communication system and the existing designs in the crucial 1-10 GHz bandwidth suffer many drawbacks. For...
