It has long been controversial whether there is an intermediate dark state between the S2 and S1 states of carotenoids.1 Recent two-dimensional electronic s
Atomistic dimensional neural networks(ANNs)have been widely used to fit the potential energy surface.ANNs can be used for fitting a very large system includ
Noncovalent interactions play important roles in the physical and life sciences,and therefore,developing and assessing advanced density functionals for nonc
We present the development of a tunable,narrow-bandwidth optical parametric oscillator(OPO)system and its applications in high resolution spectroscopy of fr
