In the third shell (n=3), we have: The 3s orbital; The 3p orbitals; The 3d orbitals; In the fourth shell (n=4), we have: The 4s orbital; The 4p orbitals; The 4d orbitals; The 4f orbitals; So another kind of orbitals (s, p, d, f) becomes available as we go to a shell with higher n. The number in front of the letter signifies which shell the ...
Run an NMR single-point calculation with the following route section in GAUSSIAN. #n B3LYP/6-31G(d,p) nmr=(fconly,readatoms) iop(3/10=1100000) At the end of the molecule specification (separated by a blank line) read in: atoms=H. A sample input file for chloroethane could be like:

$\begingroup$ But even if you include the Opt keyword in frequency calculations for an already optimized input geometry it would not harm: the program will just run 1 geometry optimization cycle and then switch to frequency calculation.
%nprocshared=4 %mem=4gb %chk=fohsdft3 # opt freq b2plypd3/aug-cc-pvdz scf=tight Input file taken from fohsdft 0 1 O -3.46278 2.54045 0. H -2.50278 2.54045 0. H -3.78324 3.44539 0. Since B2PLYP-D3 is a method, it goes where the density functional is normally specified.
Reaction solvent is toluene in which the catalysts also dissolve. Many texts said that celite pad can filtrate these catalysts, but I failed. I tried vacuum filtration using buchner filter, and poured $\pu{0.0087 g}$ $\ce{Pd2(dba)3}$ in $\approx \pu{25 mL}$ toluene. $\ce{Pd2(dba)3}$ in toluene has dark red color, but filtrate also has same ...
If you want to check your overall precision the procedure is to run complete replicate samples on the one sample or [even on simultaneous replicate samples to check on the sampling technique]. Since only 2 or 3 replicates are usually run, when readings are to the first insignificant figure a simple average is sufficient and the range is a good ...
Even if you consider a batch-wise process of generating ammonia (which, as orthocresol points out, isn’t the case), it is more efficient to run two batches in half the time for two sets of $15~\%$ than to run a single batch for twice the time to get an overall yield of maybe (note: This yield is a ballpark estimate) $25~\%$ — with a batch ...
Making predictions about elution order is always guesswork but based on my experience I would expect acetic acid to streak off the baseline, The benzyl alcohol to be of low Rf but above the acetic acid, the benzyl acetate Y to run high and I really don't know about the acetic anhydride, I suspect it will hydrolyse on the plate to give you more acetic acid so you will not see a separate spot.
