General Questions and Answers / how to link dithiocarboxylate in two probe system
« on: February 10, 2012, 06:33 »
Hello,
Can any one tell me what modifications I should make in the script to replace thiol(-S) anchoring group by dithiocrboxylate(-CS2) linking group in the given script (which is showing dithiol molecule sandwitched between two gold electrodes):
