Furthermore, the excited electron is quantum entangled to another electron so it is simultaneously in both the singlet and triplet states.
12.
The heavy metal atom at the centre of these complexes exhibits strong spin-orbit coupling, facilitating intersystem crossing between triplet states.
13.
The excited state undergoes an intersystem crossing from the singlet state to a triplet state in which there are two electrons with parallel spin.
14.
The three lowest triplet states of He 2 have designations a 3 ? u, b 3 ? g and c 3 ? g.
15.
Decay from triplet states ( phosphorescence ) is spin forbidden, increasing the timescale of the transition and limiting the internal efficiency of fluorescent devices.
16.
As a result, the energy can become trapped in the triplet state with only kinetically unfavored and thus progress at significantly slower time scales.
17.
Others dimerise slowly over days . Triplet state carbenes have half-lives measured in seconds, and therefore can be observed but not stored.
18.
When one of the triplet states gets excited, it immediately decays to the T 0 state with no emission of radiation ( internal degradation ).
19.
A molecule can have a singlet state or triplet state with different energy and both states can inter-convert by a process called intersystem crossing.
20.
A viable mean-field Hamiltonian for modelling itinerant ferromagnetism coexisting with a non-unitary spin-triplet state may after diagonalization be written as:
