What is FSSH?
FSSH stands for Fewest Switched Surface Hopping and is a quantum mechanical method used to simulate the dynamics of chemical systems.
How is FSSH used?
FSSH can be applied to many different types of chemical systems including organic molecules, polyatomic systems, and semiconductor systems. It utilizes both the wave function and nuclear motion in a single calculation.
What are the benefits of using FSSH?
The main benefit of using FSSH is that it can accurately model chemical reaction trajectories with low computational cost compared to traditional methods. It can also account for non-adiabatic processes such as conical intersections or photochemical events.
Is there any downside to using FSSH?
One potential downside to using FSSH is its reliance on external programs to calculate certain properties such as energies or gradients which may have larger computational costs than traditional methods. Additionally, the accuracy of results will depend on how well these external programs are able to approximate those calculations.
Is there any special software required for using FSSH?
Yes, some special software packages are required in order to use FSSH properly such as Gaussian 09 or Turbomole 7.2. Other software packages may be used as long as they can adequately calculate energies and gradients accurately enough for the desired application of FSSH.
Final Words:
Fewest Switched Surface Hopping (FSSH) is an efficient tool for simulating complicated chemical reaction dynamics due to its ability to take into account both wavefunction and nuclear motion in a single calculation at lower computational cost compared with traditional methods; however, it does require some external software packages such as Gaussian 09 or Turbomole 7.2 in order for it work properly depending on its application.
