 Hey, this is Steven Nescherben. I'm here to help you out with just setting up a calculation for a getting energy of activation so we're gonna try a methyl bromide, so I've already selected this in the organic menu and so I'm gonna have a Methane right there, and then I'm gonna switch to getting bromide Right over here on this side So that's gonna be one reactant and then I'm gonna have another reactant, which is another bromide and I'm taking the hydrogen off and That's fine. It's more or less lined up the way I want it to do, but the way What's recommended to do this is to guess the transition states of what I'm gonna do is I'm gonna click on this bromide and then click on This carbon and then I'm gonna click on this carbon again and This is to indicate that some electrons are gonna try to attach themselves form a bond there I'm gonna do that again. I'm still in this make transition state mode But now I'm gonna click on this bond and click on that oxygen Bromine and then do that. Okay, so now I think I know where the Electrons are going and as you will have seen that there's this guess that search for transition state appears there and It's now kind of moved it more or less into the positions that we want and I'm gonna do one more thing which is go to this constrain Constrained positions Constrain distance and I'm gonna do two distances. So this one to this one and I'm gonna click on this and I want a profile and And and I'm just gonna enter a starting distance here and I have to remember what that starting distance is so that I want it to be the van der Waals distance of 3.53 and Then 1.94 so 3.53 which is already about there 53 and 1.94 for that distance Okay, and we can do steps of 10, you know, or you could do steps of 20 if you like and the the There will be another distance that I want to constrain here Which is I'm gonna click on that bond you can do that too and now I want to go from a Profile 1.93 up to our final distance, which was 3.53 So up to 3.53 Okay, so I'm I'm all good here But the last thing now we'd have to do is go up to this icon up here And I don't want transition state geometry. You have to remember to select the energy profile It seems to be pretty reliable to go through the B3 lip mode and also the total charge on this is an anion and And so that's that's how we go and then you will just submit there and after that We can talk about how to analyze the results
