1 Morse, Michael DavidThe ground state and excited ?-hole states of CuAuResonant two-photon ionization spectroscopy has been applied to jet-cooled diatomic CuAu. Eight band systems have been observed, rotationally resolved, and analyzed. The ground state is X??+ in symmetry, deriving from the 3d??Cu 5d??Au, ?? molecular configuration. Its bond length has been determined...1991
2 Miller, Joel Steven; Epstein, Arthur J.Novel co-operative magnetic properties of decamethylmanganocenium 2,3-dichloro-5,6-dicyanobenzoquinoneide, 3[Mn(C5Me5)2]:+[DDQ].-The electron-transfer salt 3[Mn(C5Me5)2]: + [DDQ].-, isomorphous to orthorhombic [Fe(C5Me5)2].+[DDQ].-, has been prepared. It exhibits a complex field-dependent magnetic phase diagram at low temperatures with evidence for ferromagnetic coupling as well as a low moment state below 4 K for zero-field ...Ferromagnetic; Electron-transfer salt; Powder diffraction1991
3 Morse, Michael DavidResonant two-photon ionization spectroscopy of coinage metal trimers: Cu?Ag, Cu?Au, and CuAgAuThe jet-cooled coinage metal triatomic molecules Cu, Ag, Cu, Au, and CuAgAu have been investigated using resonant two-photon ionization spectroscopy. One band system, labeled as the ?-x system, has been observed for each species, with origin bands at 13 188, 17 217, and 17 470 cm -?, respectively. ...1991
4 Morse, Michael DavidResonant two-photon ionization spectroscopy of jet-cooled Au?A band system of jet-cooled Au, has been located in the near infrared region of the spectrum using resonant two-photon ionization spectroscopy. The origin band is located at 13 354.15 cm-? and the system extends more than 700 cm-? further to the blue. The excited state displays a radiative lifetime...1991
5 Miller, Joel StevenRoom temperature molecular/organic-based magnetThe Du Pont / Ohio State University research team made materials in the laboratory, then tested them for magnetism. To do so, they initially moved a magnet along the outside of a sealed tube containing a small blob of experimental material and an inert gas such as argon or nitrogen. "We've done it...Bis(benzene)vanadium; Vanadium; Tetracyanoethylene; TCNE; Polymeric magnets; Room temperature1991
6 Morse, Michael DavidSpectroscopic studies of jet-cooled AgAu and Au?Resonant two-photon ionization spectroscopy has been applied to the jet-cooled Au? and AgAu molecules. Three new band systems of Au? and two new systems of the poorly characterized AgAu molecule have been observed. Excited state lifetime measurements have been made, and assignments of the excited s...1991
7 Morse, Michael DavidSpectroscopic studies of jet-cooled CuAgResonant two-photon ionization spectroscopy has been applied to jet-cooled diatomic CuAg. Four band systems have been observed, three of which have been rotationally resolved and analyzed. The ground state is X ??+ in symmetry, deriving from the 3d??cu4d??Ag?? molecular configuration. Its bond lengt...1991
8 Miller, Joel Steven; Epstein, Arthur J.Three-dimensional ordering, spin excitations, and dilution effects in the quasi-1-D ferromagnetic (DMeFc)(TCNE)The linear chain S = (1/2) molecular ferromagnet decamethylferrocenium tetracyanoethanide [(DMeFc) (TCNE)] has been studied by frequency-dependent ac susceptibility experiments. (X')(T) and (X") (T) exhibit maxima in the temperature range of 4.8 - 4.9 K, which corresponds to the transition tempe...Temperature; Transition; Magnetic1991
