NEB.tangent(central, left, right, gleft, gright)[source]#

New uphill tangent formulation

The method was described in “Improved tangent estimate in the nudged elastic band method for finding minimum energy paths and saddle points” Graeme Henkelman and Hannes Jonsson J. Chem. Phys 113 (22), 9978 (2000)

Parameters:
centralfloat

central image energy

leftfloat

left image energy

rightfloat

right image energy

gleftnp.array

gradient to left image (x_0 - x_left)

grightnp.array

gradient to right image (x_0 - x_right)
