n,$\Pi^{*}$ AND $\Pi$,$\Pi^{*}$ FLUORESCENCES IN ACRIDINE
Yau, Joseph; Kasha, Michael ( 1975 )The N-heterocyclic acridine exhibits two different fluorescences, depending on the nature of the solvent. In a hydroxylic solvent (EPA) glass, acridine exhibits a blue $\Pi$,$\Pi^{*}$ fluorescence, resembling that of the ... -
The $n->3s$ Rydberg Transition of Jet-Cooled Tetrahydropyran, 1,4-Dioxane, and 1,4-Dioxane-$d_{8}$ Studied by $2+1$ Resonance Enbanced Multiphoton Ionization
Cornish, Timothy; Baer, Tomas; Pedersen, Lee G. ( 1989 )The lowest electronic transitions of tetrahydropyran (THP), 1,4-dioxane, and 1,4-dioxane-$d_{8}$ cooled in a free jet expansion have been examined by $2+1$ REMPI spectroscopy. The transition in dioxane is not allowed in ... -
$n-\pi$ TRANSITIONS IN AZABENZENES
Orgel, Leslie E. ( 1954 )The theory of n-$\pi$ transitions in azabenzenes is discussed and it is shown that simple molecular orbital treatments using the orbitals of the ground state are not adequate to describe the upper state. A different approach ... -
$n-\pi^{\ast}$ SINGLET STATES OF THALAZINE.
Marzzacco, Charles ( 1967 )Phthalazine differs from other ortho-diazines, pyridazine and diazaphenanthrene, in having a lowest $\pi^{\ast}$orbital of $b_{2}$ rather than $a_{2}$ symmetry. This results in a symmetry forbidden $A_{2}\leftarrow A_{1}$ ... -
THE N-H STRETCHING VIBRATION BAND IN SEVERAL AROMATIC COMPOUNDS
Fuson, Nelson; Josien, Marie-Louise ( 1951 )Theoretical work recently reported on pyrrole, indole, carbazole, aniline, and diphenyl amine has included a calculation of the electron density on the nitrogen atoms of each of these $compounds^{1}$. In order to see if ... -
N-terminal α Dystroglycan (αDG-N): A Potential Serum Biomarker for Duchenne Muscular Dystrophy
Crowe, Kelly E. ( 2018-03 )Background: Duchenne Muscular Dystrophy (DMD) is a severe, progressive, neuromuscular disorder of childhood. While a number of serum factors have been identified as potential biomarkers of DMD, none, as yet, are proteins ... -
THE N.M.R. SPECTRA AND CONFORMATION OF BUTADIENE DERIVATIVES
Harris, Robin K.; Bothner-By, Aksel A. ( 1964 )The N.M.R. spectra of several butadiene derivatives have been analyzed using the computer program LAOCOON II. The molecules studied include the halogenated compounds fluoroprene, chloroprene and the three 1,4-dichlorobutadienes ... -

N=1 super Yang-Mills theory on a (3 + 1) dimensional transverse lattice with one exact supersymmetry
Harada, Motomichi; Pinsky, Stephen ( 2005-03-24 )We formulate N=1 super Yang-Mills theory in 3 + 1 dimensions on a two dimensional transverse lattice using supersymmetric discrete light-cone quantization in the large-N_c limit. This formulation is free of fermion species ... -
