At any time you may choose the molecule that you are interested in from the list below the table. Using the periodic table helps to narrow this list down.
Special Characters in the ASCII version | |
---|---|
P or Pi | Π |
D or Di | Δ |
W | Ω |
S | Σ |
X1-S | X1Σ |
A1-S | A1Σ |
J | Resultant total angular momentum quantum number, excluding nuclear spins. |
N | Rotational angular momentum quantum number, excluding electron and nuclear spins, in the case where electron spin is present. |
K | Projection of J (or N) on the symmetry axis in the limiting prolate or oblate symmetric top. |
F1 | Resultant angular momentum quantum number including nuclear spin for one nucleus. |
F | Resultant total angular momentum quantum number. |
ε | Quantum number employed when F1 is not a good quantum number. This value simply numbers the levels from lowest to highest energy for the same F quantum number. |
Vibrational quantum number. The vibrational state remains unchanged for nearly all transitions, so a single set of quantum numbers is sufficient. |
