Intersystem crossing (ISC) is an isoenergetic radiationless process involving a transition between the two electronic states with different spin multiplicity. [ 1 ] Excited electrons can undergo intersystem crossing to a degenerate state with a different spin multiplicity.
A Jablonski diagram showing the excitation of molecule A to its singlet excited state (1 A*) followed by intersystem crossing to the triplet state (3 A) that relaxes to the ground state by phosphorescence. It was used to describe absorption and emission of light by fluorescence.
Jablonski diagram indicating intersystem crossing (left) and internal conversion (right). Internal conversion is a transition from a higher to a lower electronic state in a molecule or atom. [ 1 ] It is sometimes called "radiationless de-excitation", because no photons are emitted.
Which is it then: "Intersystem crossing is a radiationless process involving a..." vs "The radiative decay /.../ phosphorescence is another manifestation of intersystem crossing"? — Preceding unsigned comment added by 84.250.10.117 15:01, 20 January 2013 (UTC)
Originally, many thước of varying lengths were in use in Vietnam, each used for different purposes. According to Hoàng Phê (1988), [1] the traditional system of units had at least two thước of different lengths before 1890, [2] the thước ta (lit. "our ruler") or thước mộc ("wooden ruler"), equal to 0.425 metres (1 ft 4.7 in), and the thước đo vải ("ruler for measuring ...
Cầu khỉ are one of the old cultural signs in Vietnam. Now in industrialized regions sometimes there is a "Competition on passing Cầu khỉ by bicycle" for remembering the taste of footbridges.

Map of ancient Asia shows location of the Âu Việt state of Nam Cương and other Viet’s kingdoms. According to folklore, prior to Chinese domination of northern and north-central Vietnam, the region was ruled by a series of kingdoms called Văn Lang with a hierarchical government, headed by Lạc Kings ( Hùng Kings ), who were served by ...
During the expansion of Vietnam some place names have become Vietnamized. Consequently, as control of different places and regions has shifted among China, Vietnam, and other Southeast Asian countries, the Vietnamese names for places can sometimes differ from the names residents of aforementioned places use, although nowadays it has become more ...
