Input and output files available for 3 geometries, in three directories and this one (general to all geometries):

bth_barrier: barrier geometry for bridge-to-hollow dissociation
ttb_barrier: barrier geometry for top-to-bridge dissociation
asy: asymptotic geometry

INCAR, KPOINTS, POSCAR: Vasp input files, POSCAR is specific to geometry
only 1st lines are provided of PW91 ultrasoft vanderbilt PP provide by VASP

Output files: OSZICAR, specific to geometry, E0 in last line is energy in eV

Barrier energies relative to asymptotic geometry are, for SRP 48 functional:
Bth: 0.6281 eV, 60.60 kJ/mol
Ttb: 0.8769 eV, 84.61 kJ/mol
