  • Phase transitions in M(ClO4)2.6H2O (M = magnesium, zinc). Investigations by adiabatic calorimetry and infrared spectroscopy. 

    Reproduced from White, Mary Anne, and Michael Falk. 1986. "Phase transitions in M(ClO4)2.6H2O (M = magnesium, zinc). Investigations by adiabatic calorimetry and infrared spectroscopy.." Journal of Chemical Physics 84(6): 3484-3490, with the permission of AIP Publishing.
    IR spectra of Mg(ClO4)2.6H2O at 10 K indicate a complex structure contg. at least 16 distinct types of H2O protons. At 107.9 K this structure transforms sharply to a much simpler disordered form (?Strans = 7.754 J K-1 ...

  • Phase transitions in metal perchlorate hydrates: the supposed hydrate-to-pseudohydrate transformations. 

    Reproduced from Falk, Michael, Ping F. Seto, and Mary Anne White. 1984. "Phase transitions in metal perchlorate hydrates: the supposed hydrate-to-pseudohydrate transformations.." Journal of Chemical Physics 81(8): 3752-3753, with the permission of AIP Publishing.
    A polemic. The hydrate-to-pseudohydrate transformations in metal perchlorate hydrates reported by M. B. Patel and H. D. Brist (ibid. 1983, 79, 4489) and Solid State Commun. (48, 139 (1983)) as well as the suggested ...

  • A study of phase transitions in cadmium perchlorate hexahydrate (Cd(ClO4)2.6H2O) by adiabatic calorimetry and infrared spectroscopy. 

    Reproduced from White, Mary Anne, and Michael Falk. 1985. "A study of phase transitions in cadmium perchlorate hexahydrate (Cd(ClO4)2.6H2O) by adiabatic calorimetry and infrared spectroscopy.." Journal of Chemical Physics 83(5): 2467-2474, with the permission of AIP Publishing.
    A calorimetric study of Cd(ClO4)2.6H2O from 20 to 345 K shows 3 phase transformations, at 124.8, 238.45, and 271.62 K. IR spectra indicate that the low-temp. structure (below 124.8 K) contains 1 type of [Cd(OH2)6]2+, of ...
