ADap­tive ANaly­sis of Inter­Mol­e­c­u­lar Ener­gy Hyper­Sur­faces

(Last update: 8.09.2007)

Adanimehs — a pro­gram for effi­cient quan­tum chem­i­cal explo­ration of poten­tial ener­gy sur­faces (PES) of struc­tural­ly non-rigid mol­e­c­u­lar com­plex­es, approx­i­ma­tion or inter­po­la­tion of PES with a mod­el con­tin­u­ous func­tion, and esti­ma­tion of ther­mo­dy­nam­ic para­me­ters of the com­plex using the semi-clas­si­cal Monte-Car­lo cal­cu­la­tions.

In com­par­i­son with oth­er tools, Adanimehs has two cru­cial advan­tages:

  • Ab ini­tio explo­ration of full (mul­ti­di­men­sion­al) inter­mol­e­c­u­lar PES instead of loca­tion of select­ed sta­tion­ary points only. 
  • Cal­cu­la­tion of ther­mo­dy­nam­ic prop­er­ties in the approx­i­ma­tion high­er than the usu­al­ly employed RRHO mod­el. It allows obtain­ing the high-accu­rate val­ues of equi­lib­ri­um con­stants and con­cen­tra­tions for weak­ly bound sys­tems like van-der-Waals and H-bond­ed com­plex­es or clus­ters.

  • Impor­tant notice: Adanimehs is a research soft­ware under devel­op­ment and dis­trib­uted on “as is” basis. There are no war­ran­ty that it is free of unde­tect­ed bugs and mis­takes. Please refer the revi­sion his­to­ry for the bugs cor­rect­ed in pre­vi­ous ver­sions. We should appre­ci­ate receiv­ing any com­ments, advices, bug reports, and the requests for fur­ther improve­ments.
