text: Nitroso or nitrone compounds "trap" this quantity by forming an adduct measured in EPRspectroscopy.
full_question: Nitroso or nitrone compounds "trap" this quantity by forming an adduct measured in EPRspectroscopy. This quantity is high for octahedral complexes with low splitting energy. Coupling of thisquantity makes doublets and triplets with peak ratios given by Pascal's triangle. This quantity allowsmolecular orbitals to be antisymmetric. In NMR, a magnetic field (*) "flips" this quantity. Hund's rule ofmaximum multiplicity says that atoms maximize the total amount of this quantity. A single-barbed arrow representsthis vector quantity in configuration diagrams. Two electrons in the same orbital must have the opposite value forthis quantity by the Pauli exclusion principle. For 10 points, name this measure of intrinsic angular momentum.
first_sentence: Nitroso or nitrone compounds "trap" this quantity by forming an adduct measured in EPRspectroscopy.
raw_answer: spin [do not accept or prompt on "angular momentum"]
