Experimental study of the frequency factor in the Polanyi-Wigner equation: the case of C2H6

Luna Molina, Ramón; Millán Verdú, Carlos; Domingo Beltran, Manuel; Santonja Moltó, Mª del Carmen; Satorre, M. Á. (Elsevier, 2015-12)

The C2H6 molecule has been used to determine experimentally, for the first time, the frequency factor present in the Polanyi-Wigner equation and to study how temperature influences this magnitude for a zeroth order desorption. ...
Study of the frequency factor in the thermal desorption of astrophysical ice analogs: CH4, C2H4, C2H6, CH3OH, CO, CO2, H2O and N2

Luna Molina, Ramón; Domingo Beltran, Manuel; Millán Verdú, Carlos; Santonja Moltó, Mª Del Carmen; Satorre, M. Á. (Elsevier, 2018)

[EN] In this work the frequency factor and the influence of the temperature on this parameter, for zeroth order desorption processes, has been experimentally determined for eight molecules of astrophysical interest. In the ...
Upgraded sublimation energy determination procedure for icy films

Luna Molina, Ramón; Millán Verdú, Carlos; Domingo Beltran, Manuel; Santonja Moltó, Mª del Carmen; Satorre Aznar, Miguel Ángel (Elsevier, 2012-06-20)

A method to determine the sublimation energy of a bulk ice in high vacuum systems, allowing other simultaneous analysis techniques, is presented. Variation in frequency of a quartz crystal microbalance, due to sublimating ...
