A singlet is a sleeveless dress-like piece of clothing worn under a piece of clothing, somewhat like a slip. A doublet is a male jacket, and has not been popular since the 17th century.
A singlet in chemistry is a peak or band that has only one peak. A doublet is a peak or band of similar intensity, located right next to or slightly merged with the other.
In NMR spectroscopy, a Doublet of doublet is a signal that is split into a doublet, and each line of this doublet split again into a doublet. Occurs when coupling constants are unequal.
In theoretical physics, a singlet usually refers to a one-dimensional representation (e.g. a particle with vanishing spin). It may also refer to two or more particles prepared in a correlated state, such that the total angular momentum of the state is zero.Singlets frequently occur in atomic physics as one of the two ways in which the spin of two electrons can be combined; the other being a triplet. A single electron has spin 1/2, and transforms as a doublet, that is, as the fundamental representation of the rotation group SU(2). The product of two doublet representations can be decomposed into the sum of the adjoint representation (the triplet) and the trivial representation, the singlet. More prosaically, a pair of electron spins can be combined to form a state of total spin 1 and a state of spin 0.The singlet state formed from a pair of electrons has many peculiar properties, and plays a fundamental role in the EPR paradox and quantum entanglement. In Dirac notation this EPR state is usually represented as:
singlet
8 Neutrons in singlet oxygen
Michel Doublet was born in 1939.
Georges Doublet has written: 'Godeau'
This is the singlet by the way http://24mediatumblrcom/tumblr m09d7s9dsn1qg7w0qo1 500jpg
That is the correct spelling of the noun "doublet" (a matched pair, or a jacket).
Marie Anne Doublet was born in 1677.
Marie Anne Doublet died in 1771.
