Hello and welcome to a quick overview of the molecule calculator. We start here in the molecule editor window where I can build my molecules. So for example here I can add another carbon here. I can add an nitrogen here. I can change the charge of this atom so that it's now an NH3 plus. I can make this a double bond for example. I can minimize it to get a better structure. And now for example now I'm ready for a calculation on this molecule. So I hit calculate here. Yes I'm sure. And now it prepares the calculation. And so in this version of the molecule calculator, molecule calculator 1.0, I have three options, three things I can calculate. So for example I can calculate the heat of formation. That's done. Right and you can see then I have the heat of formation here in kilocalories for more. I can also load results. And for this particular thing, this particular property that just brings the result into the window here. I can also calculate molecular orbitals. Okay and I have to remember to load the orbitals here and now I can go in. The orbitals are ranked by orbital energies. So for example I can pick this one here. Right and here I have the molecular orbital which is primarily associated with the nitrogen group. I can scroll down. For example here you can see the pi bond. The final thing is vibrational frequencies. So I have to load results. This is the here ranked by vibrational frequencies or vibrational wave numbers. This is the lowest vibrational frequency here. And if I see how that looks, I can see that here. I can also add vectors here and I can also turn off the atoms to get a more simplified view of the molecule. So let me turn that off. I can always go back. Remember that I already calculated the heat of formation here. I can load that and here I have my molecule again. I can also go in and measure distances. So this is the way the program we used to view the molecule is called J-mo. J-mo can do a lot of different things. For example if I double click on this atom and drag. Right, I get distances or I can get angles. Oops, I have to double click to finish. Okay. And finally I can get the heat of angles. Double click, single click, single click, double click. And so that's the the heat of angles here. Finally by right clicking I get access to all the different things that J-mo can do. So for example here I'm going in measurements and pick angstroms. Instead if I prefer that. So here the bond length is one angstrom. And so that's a quick overview of molecular calculator.
