The second volume, published in 1912 as Clarke's Technical Studies for Cornet, includes 190 exercises divided into ten studies with notes from the author suggesting how to practice them. Each of the ten studies concludes with an exercise serving as an étude , except for the ninth study, which lacks an exercise labeled as such, and the tenth ...
Examples of atoms in singlet, doublet, and triplet states.. In quantum mechanics, a doublet is a composite quantum state of a system with an effective spin of 1/2, such that there are two allowed values of the spin component, −1/2 and +1/2.
The triplet consists of three states with spin components +1, 0 and –1 along the direction of the total orbital angular momentum, which is also 1 as indicated by the letter P. The total angular momentum quantum number J can vary from L+S = 2 to L–S = 0 in integer steps, so that J = 2, 1 or 0.
Examples of atoms in singlet, doublet, and triplet states. In quantum mechanics, a triplet state, or spin triplet, is the quantum state of an object such as an electron, atom, or molecule, having a quantum spin S = 1. It has three allowed values of the spin's projection along a given axis m S = −1, 0, or +1, giving the name "triplet".
The second law is offered as a simple observation in the same essay but its status as Clarke's second law was conferred by others. It was initially a derivative of the first law and formally became Clarke's second law where the author proposed the third law in the 1973 revision of Profiles of the Future, which included an acknowledgement.

In computational chemistry, spin contamination is the artificial mixing of different electronic spin-states.This can occur when an approximate orbital-based wave function is represented in an unrestricted form – that is, when the spatial parts of α and β spin-orbitals are permitted to differ.
Having triplets across two uteruses? Even more so. However, Sadie has company: In 2006, a 23-year-old British woman had triplets across two uteruses — twins who grew in one uterus, and another ...
In particle physics, the doublet–triplet (splitting) problem is a problem of some Grand Unified Theories, such as SU(5), SO(10), and . Grand unified theories predict Higgs bosons (doublets of S U ( 2 ) {\displaystyle SU(2)} ) arise from representations of the unified group that contain other states, in particular, states that are triplets of ...
