Triplet-triplet annihilation (TTA) is the energy transfer process where two molecules in their triplet excited state interact to produce two singlet states.

Singlet: In NMR spectroscopy, asignal which is not split; i.e., it is a single line. An idealized singlet. An idealized doublet. An idealized triplet. This simulated1H-NMR spectrum of 2-ethylphenol includes a multiplet at 6.6-7.2 ppm, a singlet at 6.0 ppm, a quartet at 2.4 ppm, an...
Vocabulary.com had a good explanation of “what is a dilemma,” but they usually do. Vocabulary.com presents clear, concise definitions in plain English, whereas many of the other dictionary options present definitions that often require a person look up one or two more words to understand what...
A prime triplet is a set of three prime numbers that can be represented in the following form: (p,p+2,p+6) or (p,p+4,p+6), where p is a prime number.For example: (5, 7, 11) and (7, 11, 13)Co-prime NumbersTwo numbers that have just 1 as a common factor are co-...

This process of cell division is called mitosis. A few days after fertilization, the zygote reaches the 32-cell state, known as morula. The morula is a solid cluster of cells. A few days later – starting about five days after fertilization – the morula becomes a blastocyst, a hollow ...
states that fluorescence will always originate from the vibrational ground state of the lowest excited singlet level, the S1, while phosphorescence will originate from the vibrational ground state of the lowest excited triplet level, the T1, regardless of which initial level the molecule is excited ...
The triplet peak at 3.74 ppm with an integral value of 4 is indicative of the four protons surrounding the oxygen in the ring structure while the triplet peak at 2.51 ppm with an integral value of 4 is conclusive of the protons surrounding the nitrogen in the ring structure. Finally, the ...
