Unit 1 Mole and enthalpy changes
... Thermochemistry is the study of heat energy taken in or given out in chemical reactions. This heat, absorbed or released, can be related to the internal energy of the substances involved. Such internal energy is called ENTHALPY, symbol H. As it is only possible to measure the change in enthalpy, the ...

1.1 Applications of Cold Molecules
... The dipole moment is a measure for the charge distribution of the particle. Since the electron is assumed to be a point charge, however, the EDM is considered to be a measure of the average displacement of the electron charge from the electron’s center of mass. An EDM would imply an asymmetry with r ...
