Why does the decay time decrease with increase in water fraction in solvent mixture?

Decay time of a molecule having charge transfer character shows decrease in life time with increasing amount of water in THF/Water system. Quantum yield also decrease along with red shift. But the...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...
