What is the concept of singlet state?

Singlet state is defined when all the electron spins are paired in the molecular electronic state and the electronic energy levels do not split when the molecule is exposed into a magnetic field. A singlet or a triplet can form when one electron is excited to a higher energy level. In an excited singlet state, the electron is promoted in the same spin orientation as it was in the ground state (paired).

How to Calculate Singlet Life Time of Radiative Process?

Singlet Life Time of Radiative Process calculator uses Singlet Life time of Radiative Process = ((Initial Intensity/Fluorosence Intensity)-1)/(Quenching Constant*Quencher Concentration given Degree of Exciplex) to calculate the Singlet Life time of Radiative Process, Singlet Life Time of Radiative Process is the characteristic time that a molecule remains in its excited state before returning to the ground state.
