If "example 1" and "example 2" are examples of a single lines (i.e. they do not span multiple lines in your text file), then here's a way to do it with Perl:

Code:
$
$ cat -n f1
     1  2.524075,-0.563322,-1.285286\H,0,-2.544438,-0.678834,1.199166\H,0,2.185962,-1.978001,0.018499\\Version=EM64T-G03RevE.01\State=5-A\HF=-1277.1557592\S2=6.033269\S2-1=0.\S2A=6.000179\RMSD=8.037e-05\Thermal=0.\Dipole=-0.1643425,0.9094768,0.0321427\PG=C01 [X(C4H9Cr1O1)]\\@
     2  6256\H,0,-2.980236,0.00009,-0.45647\\Version=EM64T-G03RevE.01\State=5-A\HF=-1198.5241253\S2=6.077753\S2-1=0.\S2A=6.000457\RMSD=4.977e-05\Thermal=0.\Dipole=0.8534315,0.002042,-0.5745813\PG=C01 [X(C2H5Cr1O1)]\\@
$
$ perl -lne '/.*(HF=[^\\]+)\\.*/ and print $1' f1
HF=-1277.1557592
HF=-1198.5241253
$
$

You can redirect the output to a new file using the shell's redirection operator.

Sorry, did not read your post carefully.
For the ones that span multiple lines, here's how you can do it with Perl:

Code:
$
$ cat -n f2
