potential energy surfaces - 2024 Chicago Open

Question

Tersoff and Brenner developed the REBO model of these theoretical constructs. (-5[1])In the Tinker software package, these constructs are analyzed using the GDA and SCAN programs. A simple one of these constructs has three parameters, including the coupling constant a equal to [read slowly] “the square root of the force constant divided by the well depth divided by 2.” To locate certain points on these constructs, Peng and Schlegel combined quasi-Newton and (15[3])synchronous transit methods. (15[1])A Hessian matrix (15[1])is created for (10[1])(*) stationary points on these constructs using geometry optimization. They’re not bands, but at conical intersections on these constructs, the Born–Oppenheimer approximation breaks down. A type of (10[1])these constructs that uses an anharmonic oscillator to model diatomic systems is named (-5[3])for Morse. (10[2]-5[1])Saddle points on these graphs correspond to transition states. For 10 points, name these graphs that model a namesake variable in terms of atom (10[3]0[1])positions. ■END■

ANSWER: potential energy surfaces [or PES; or potential energy landscapes, potential energy functions, potential energy hypersurfaces, or potential energy profiles; accept Morse potentials or Morse/Long-range potentials or MLR potentials until “Morse” is read; prompt on More O’Ferrall–Jencks plots; prompt on reaction coordinate diagrams; prompt on potential energy or energy or surfaces or landscapes; prompt on potentials by asking “which are used to generate what constructs?”]
