A fundamental and long-standing question surrounds the mechanism of primary bond cleavage in azoalkanes: do the two C-N bonds break in a synchronous or a stepwise manner? When a vapor phase azoalkane absorbs near ultraviolet ...

An ultra high vacuum chamber was constructed to study thin film growth using scanning tunneling microscopy (STM). The sample stage is specially designed so that samples can be transferred in situ among various film preparation ...

Ab initio calculations of the electronic structure of bulk materials and large clusters are not possible on today's computers using current techniques. The storage and diagonalization of the Hamiltonian matrix are the ...

The new third form of carbon, known collectively as fullerenes, is studied in several general aspects. Efficient production methods have been developed along with an increased understanding into the formation mechanisms. ...

In the first application of a new method for determining this information, rates of collisional vibrational energy removal have been measured for the T$\sb1$ state of pyrazine with vibrational energy contents ranging from ...

A new apparatus capable of combining an external laser vaporization supersonic cluster beam source with a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer has been designed and implemented. Cluster ions ...

To address the relative lack of understanding concerning growth mechanisms for diamond chemical vapor deposition (CVD), this work explores kinetics of diamond epitaxy--growth on single-crystal substrates--and morphology ...

Photoelectron spectra of negatively charged cobalt clusters in the size range of 4-26 atoms have been obtained. The electron affinity (E.A.) values along with the reported ionization potential (I.P.) have been used to ...

Equilibrium concentrations of the major species in conventional and halogen assisted CVD diamond synthesis systems were calculated and the results are presented in this thesis. The optimal diamond deposition conditions ...

Collisional energy removal rates from vibrationally excited T$\sb1$ pyrazine are measured using the refined and validated Competitive Radiationless Decay (CRD) method. Optical excitation followed by intersystem crossing ...
