What is NX?


Surface hopping
NX is a general-purpose program package for excited-state molecular dynamics, including nonadiabatic methods (Trajectory Surface Hopping).

Spectrum simulations
NX can be used to simulate absorption and emission spectra with the nuclear ensemble approach.

Modularity
NX modular development allows it to be easily linked to any quantum chemistry package that can provide energy gradients and nonadiabatic couplings.

Documentation and Tutorial


Current version (2.0)
In the current version, NX can perform nonadiabatic dynamics using COLUMBUS (MRCI and MCSCF), TURBOMOLE (TDDFT, ADC(2), and CC2), GAUSSIAN (TD(U)DFT, TD(U)DFT/TDA, (U)CIS, and CASSCF), and GAMESS (MCSCF) program packages.

NX 2.0 can also compute Dyson orbitals and simulate steady and time-resolved photoelectron spectra (TDDFT with GAUSSIAN and with an optional interface to ezDyson).
