The low temperature crystalline and glassy states of methyl -hydroxy-isobutyrate
Jarmelo, Susana; Maria, Teresa M. R.; Leitão, Maria Luísa P.; Fausto, RuiThe low temperature crystalline and glassy phases of methyl -hydroxy-isobutyrate (MHib) were identified and characterized structurally by differential scanning calorimetry, IR and Raman spectroscopy and molecular modeling. Within the temperature range 13–171 K, MHib exists as a glassy state, where individual molecules may assume the two conformational states previously observed for this compound isolated in an ...
Structural and vibrational characterization of methyl glycolate in the low temp...
Jarmelo, Susana; Maria, Teresa M. R.; Leitão, Maria Luísa P.; Fausto, RuiThe low temperature phases of methyl glycolate (MGly) were identified and characterized structurally by differential scanning calorimetry, infrared and Raman spectroscopies and molecular modeling. Within the temperature range 13–273 K, MGly may exist in three solid phases. A crystalline phase (I) can be formed from the liquid upon slow cooling [Tonset=222–227 K] or from the low temperature glassy state resultin...
