I am attempting to optimise the geometry of the ionic product of a gas-phase reaction, using Gaussview 5 as a GUI for Gaussian 09 and the default settings for the program. When I submit the job, I obtain a message saying that the job can not run because of severe error 2070. Can anybody explain what this error means (I have had a look online and can not find anything useful) and how to prevent it from happening? Happy to share further information offline. Best wishes, Stephen Holman
