Intersystemcrossing is a radiationless process involving a transition between two electronic states with different spin multiplicity . ref GoldBookRef title Intersystemcrossing file I03123 ref File Electronic Processes Involving Light.png thumb Excited electrons can undergo intersystemcrossing to a degenerate state with a different spin multiplicity. Singlet and triplet states When an electron in a molecule with a singlet ground state is excited via absorption of radiation to a higher energy level, either an excited singlet state or an excited triplet state will form. A singlet state is a molecular electronic state such that all Electron spin electron spins are paired. That is, the spin of the excited electron is still paired with the ground state electron a pair of electrons in the same energy level must have opposite spins, per the Pauli exclusion principle . In a triplet state the excited electron is no longer paired with the ground state electron that is, they are parallel same spin . Since excitation to a triplet state involves an additional forbidden spin transition, it is more probable that an excited singlet will form upon absorption of radiation. Image ISC excited states.png thumb 300 px right Singlet and triplet energy levels. When a singlet state nonradiatively transitions to a triplet state, or conversely a triplet transitions to a singlet, that process is known as intersystemcrossing. In essence, the spin of the excited electron is reversed.

Crossing the T or Capping the T is a classic naval warfare tactic attempted from the late 19th to mid 20th century, in which a line of warship s crossed in front of a line of enemy ships, allowing the crossing line to bring all their guns to bear while receiving fire from only the forward guns of the enemy. ref cite book title Fleet tactics and coastal combat last Hughes first Wayne P. authorlink coauthors year 2000 publisher Naval Institute Press location isbn 9781557503923 page 74 pages url accessdate ref It became possible to bring all of a ship s main guns to bear only in the late 19th and the early 20th centuries with the advent of steam powered battleships with rotating gun turrets, which were able to move faster and turn quicker than sailing ships, which had fixed guns facing sideways. The tactic became largely obsolete with the introduction of missile s and aircraft as long range strikes are not dependent on the direction the ships are facing. Tactics When going into battle, ships would assume a battle line formation called line astern , in which one vessel followed another in one or more parallel lines. This allowed each ship to fire over wide arcs without lofting salvo salvos of Shell projectile projectiles over friendly vessels. Each ship in the line generally engaged its opposite number in the enemy battle line which moved in a Parallel geometry parallel course.

A green bicycle is displayed next to the green man when cyclists and pedestrians are permitted to cross. Additionally, unlike the pelican crossing, before the lights for vehicles go back to green, a steady red and amber are displayed instead of a flashing amber. The pedestrian cyclist signal lights may be on the near side of the crossing like a puffin crossing , or on the opposite side of the road like a pelican crossing . Signalled cycle only crossings also exist, linking cycle tracks on opposite sides of the road. Cycles may be ridden or walked across, but not until the green cycle symbol is showing. ref The Highway Code , Rule 81 ref However, cycling across against a Red Cycle is not illegal, in contrast to cycling through a red light.

In a typically oriented church especially of Romanesque architecture Romanesque and Gothic architecture Gothic styles , the crossing gives access to the nave on the west, the transept arms on the north and south, and the quire architecture choir on the east. The crossing is sometimes surmounted by a tower or dome . A large crossing tower is particularly common on English Gothic architecture Gothic cathedrals. With the Renaissance , building a dome above the crossing became popular. Because the crossing is open on four sides, the weight of the tower or dome rests heavily on the corners a stable construction thus required great skill on the part of the builders.
