  • Observation of the high resolution infrared absorption spectrum of CO₂ molecules isolated in solid parahydrogen 
    Tam, Simon; Fajardo, Mario E. (Физика низких температур, 2000)
    We report the observation of high resolution (0.008 cm⁻¹) infrared absorption spectra of CO₂ molecules isolated in solid parahydrogen(pH₂) matrices at T=2.4 to 4.8 K. Several extremely sharp (0.01 to 0.04 cm⁻¹ full-width ...
  • Optical spectra of CuO₂ and matrix effect upon its structure 
    Caspary, Nico; Savchenko, Elena V.; Thoma, Anton; Lammers, Andreas; Bondybey, Vladimir E. (Физика низких температур, 2000)
    Optical absorption and laser-induced fluorescence (LIF) spectra of CuO₂ in solid matrices are investigated, and previous visible studies are extended into the infrared. Several new electronic states are observed and their ...
  • Physical aspects of matrix isolation technique: FTIR studies on CO and CO₂ in O₂ and N₂ matrices 
    Minenko, Maksym; Vetter, Martin; Brodyanski, Alexander P.; Jodl, Hans J. (Физика низких температур, 2000)
    The matrix isolation technique is traditionally used to investigate the properties of the matrix-isolated species themselves or to solve some special questions of the theory of defects in solid. We showed here that the ...
  • Properties of solid ³He inclusions embedded in crystalline ⁴He matrix at ultralow temperatures 
    Ganshin, A.; Grigor`ev, V.; Maidanov, V.; Mikhin, N.; Penzev, A.; Polev, A.; Rudavskii, E.; Rybalko, A. (Физика низких температур, 2000)
    A study is made of the kinetic properties of the quantum systems formed in dilute solid mixtures of ³He in ⁴He at ultralow temperatures as a result of the first-order phase transition known as phase separation. The system ...
  • Reactions of laser-ablated aluminum atoms with nitrogen during condensation at 10 K. Infrared spectra and density functional calculations for Alx Ny molecular 
    Andrews, Lester; Zhou, Mingfei; Chertihin, George V.; Bare, William D.; Hannachi, Yacine (Физика низких температур, 2000)
    Laser-ablated aluminum atoms react with dinitrogen on condensation at 10 K to form N₃ radicals and the subject molecules, which are identified by nitrogen isotopic substitution, further reactions on annealing, and comparison ...
  • Rovibrational transitions and nuclear spin conversion of methane in parahydrogen crystals 
    Miki, Masaaki; Momose, Takamasa (Физика низких температур, 2000)
    Solid parahydrogen is an excellent matrix for matrix-isolation spectroscopy because of its high spectral resolution. Here we describe the rovibrational structure and nuclear spin conversion of CH₄ embedded in parahydrogen ...
  • Sound propagation in liquid He in impurity-helium solids 
    Kiselev, S.I.; Khmelenko, V.V.; Lee, D.M. (Физика низких температур, 2000)
    The observed features of the attenuation of ultrasound in Im–He samples created after the introduction of impurity particles (D₂,N₂, Ne, Kr) in a volume of helium II show that a porous substance consisting of a loosely ...
  • Spectroscopy of yttrium dimers in argon matrices 
    Fang, Li; Chen, Xiaoyu; Shen, Xiaole; Liu, Yifei; Lindsay, D.M.; Lombardi, John R. (Физика низких температур, 2000)
    The absorption and resonance Raman spectra of yttrium dimers (Y₂) in argon matrices are measured for the first time. The absorption spectrum (scattering depletion spectrum SDS) shows a weak, broad transition centered near ...
  • Structure characteristics of methane-doped solid normal hydrogen 
    Galtsov, N.N.; Prokhvatilov, A.I.; Strzhemechny, M.A. (Физика низких температур, 2000)
    Structure studies of the quantum crystal of solid normal hydrogen doped with methane and deuteromethane are carried out by powder x-ray diffraction within the temperature range 5 to 12 K. The concentration of the dopants ...
  • Thermal conductivity of solid krypton with methane admixture 
    Dudkin, V.V.; Gorodilov, B.Ya.; Krivchikov, A.I.; Manzhelii, V.G. (Физика низких температур, 2000)
    The thermal conductivity of CH₄–Kr solid solutions is investigated at CH₄ concentrations 0.2–5.0% in the temperature range 1.8–40 K. It is found that the temperature dependence of the thermal conductivity has features ...
