The rate at which the net value of this quantity exponentially decays to zero can be measured using a Hahn echo and is characterized by the T2 relaxation time.
The rate at which the net value of this quantity exponentially decays to zero can be measured using a Hahn echo and is characterized by the T2 relaxation time. This quantity changes during intersystem crossing. According to the selection rules for electronic transitions, the net change in this quantity for an electronic transition MUST be zero. The difference between fluorescence and phosphorescence is that this quantity changes in phosphorescence as a (*) triplet state is converted to a singlet state. Only isotopes with a nonzero total value of this quantity can be used in NMR. An electronic configuration possessing the highest value for this quantity has the lowest energy according to Hund's first rule. For 10 points, name this quantity which for electrons is the fourth quantum number and takes on values of plus or minus one half.
