  • Activation spectroscopy of electronically induced defects in solid Ne 
    Grigorashchenko, O.N.; Rudenkov, V.V.; Khizhnyi, I.V.; Savchenko, E.V.; Frankowski, M.; Smith-Gicklhorn, A.M.; Beyer, M.K.; Bondybey, V.E. (Физика низких температур, 2003)
    Thermally stimulated luminescence (TSL) and thermally stimulated exoelectron emission (TSEE) methods were used in combination with cathodoluminescence to probe electronically induced defects in solid Ne. The defects were ...
  • Exciton self-trapping into diatomic and triatomic molecular complexes in xenon cryocrystals 
    Ogurtsov, A.N.; Savchenko, E.V.; Sombrowski, E.; Vielhauer, S.; Zimmerer, G. (Физика низких температур, 2003)
    The recent study of molecular trapped centers in Xe cryocrystals was extended on triatomic self-trapped excitons. Time- and spectrally-resolved molecular luminescence was measured in the temperature range 5–60 K. The ...
  • Kr–Cl stretching vibration of HKrCl: Matrix-isolation and anharmonic ab initio study 
    Lignell, Antti; Lundell, Jan; Pettersson, Mika; Khriachtchev, Leonid; Räsänen, Markku (Физика низких температур, 2003)
    The Kr–Cl stretching vibration of HKrCl molecule is studied. The absorption shows ³⁵Cl and ³⁷Cl isotopic splitting due to natural abundance of the Cl isotopes. The observed Kr–Cl stretching vibrations of the HKrCl are at ...
  • Luminescence and formation of alkalihalide ionic excimers in solid Ne and Ar 
    Śliwiński, G.; Frankowski, M.; Schwentner, N. (Физика низких температур, 2003)
    Transitions from ionic states A²⁺X– of alkalihalides CsF, CsCl and RbF isolated in solid Ne and Ar films recorded under pulsed e-beam excitation are studied. The B(²∑₁/₂)-X(²∑₁/₂) and C(²П₃/₂)-A(²П₃/₂) luminescence bands ...
  • Matrix-isolation FTIR study of azidoacetone and azidoacetonitrile 
    Frankowski, Marcin; Algarra, Manuel; Rodrigues, Paula; Barros, Maria T.; D.S. Cordeiro, M. Natália; Fox, Brigitte S.; Smith-Gicklhorn, Alice M.; Beyer, Martin K.; Costa, Maria L.; Bondybey, Vladimir E. (Физика низких температур, 2003)
    Azidoacetonitrile (N₃CH₂CN) and azidoacetone (N₃CH₂COCH₃) were studied by matrix-isolation FTIR spectroscopy in solid neon, argon and nitrogen. The IR spectra calculated using the density fuctional theoretical method are ...
  • Monte Carlo simulations of krypton adsorption in nanopores: Influence of pore wall heterogeneity on the adsorption mechanism 
    Kuchta, Bogdan; Llewellyn, Philip; Denoyel, Renaud; Firlej, Lucyna (Физика низких температур, 2003)
    We present molecular simulation results of the adsorption of krypton in a model of MCM-41 mesoporous material. The adsorption isotherm and adsorption enthalpies have been studied at 77 K. The comparison of experimental and ...
  • Prompt and delayed secondary excitons in rare gas solids 
    Kirm, M.; Kisand, V.; Sombrowski, E.; Steeg, B.; Vielhauer, S.; Zimmerer, G. (Физика низких температур, 2003)
    Direct and indirect creation of excitons in rare gas solids has been investigated with reflectivity and luminescence spectroscopy. For the heavy rare gas solids Kr and Xe, new and more reliable exciton parameters have been ...
  • Purely electronic zero-phonon line as the foundation stone for high-resolution matrix spectroscopy, single-impurity-molecule spectroscopy, and persistent spectral hole burning. Recent developments 
    Rebane, K.K. (Физика низких температур, 2003)
    A few examples of recent progress in the study and applications of purely electronic zerophonon line (ZPL) and its offshoots are briefly considered: new experimental values of the narrowest ZPL; time-and-space-domain ...
  • Quantum property of solid hydrogen as revealed by high-resolution laser spectroscopy 
    Hiroyuki Katsuki; Mizuho Fushitani; Takamasa Momose (Физика низких температур, 2003)
    Pure vibrational overtone transitions of solid parahydrogen were studied using high-resolution laser spectroscopy. Extremely narrow spectral linewidth (~20 MHz) allowed us to observe rich spectral structure that originates ...
  • Temperature dependence of hot luminescence in solid xenon: theory and experiment 
    Selg, Matti; Kink, Rein (Физика низких температур, 2003)
    Vibrational relaxation of self-trapped excitons in solid xenon has been investigated both experimentally and theoretically. Hot luminescence spectra of the crystal have been measured in a wide temperature range (from liquid ...
  • The vibrational relaxation of CO₂ isolated in solid argon 
    Cenian, A.; Grigorian, G.; Śliwiński, G. (Физика низких температур, 2003)
    For description of the vibrational relaxation of CO₂ molecules embedded in Ar matrix the model based on multiphonon transitions is applied. Rates for the VT and VV processes are determined from a fitting of simulated and ...
  • The vibration-rotation of H₂O and its complexation with CO₂ in solid argon revisited 
    Michaut, Xavier; Vasserot, Anne-Marie; Abouaf-Marguin, Luce (Физика низких температур, 2003)
    Fourier-transform infrared spectroscopy in the frequency range 400–4000 cm–¹ has been used to investigate the absorption of H₂O and H₂O:CO₂ complex isolated in solid argon. Thanks to the lowest temperature reached in our ...
