'make' does not generate gar2ped.exe file instead it generate gar2ped.x file. 'pullarc' reads the archieve file from Gaussian output file but gar2ped (or gar2ped.x) does not work properly. Does anyone have a correct version of gar2ped to calculate PED?

Hello!

To add the ECP to the particular atom in GAUSSIAN0X (X= 3 or 9), as addition to the basis set which will describe the valence electrons (first part of the  the aug-cc-pVXZ-PP in EMLS called by the GEN keyword) you have to add the keyword "Pseudo=read" and write the particular ECP (as the 'identifier word, for instance LanL2DZ, or explicitly in the appropriated format as the EMLS - see http://www.nd.edu/~wschnei1/Courses/CBE_547/g03_man/g_ur/k_pseudo.htm or the GAUSSIAN09 manual-).

In the EMLS basis set the ECP description starts with
I     0
I-ECP 4 28
Otherwise, despite the calculation finished without errors apparently, you will obtain wrong results...
I guess that the wrong results arise from the bad description of the atom which is supposed to take an ECP for the core eletrons.

In other words, GAUSSIAN doesn't assign the ECP to the atom if the "Pseudo=read" keywords are not present, but the calculation run...

You can use ECP in Gaussian calculation (see pseuso=3Drea= d).
Please have a look at this=A0 Theor. Chem. Acc. 2009= , 122, 119, on iodine calc= ulation.

In Gaussian 03, it is apparently not possible to use ECP basis sets
using the GEN keyword. I thus need to find an all-electron basis set
for iodine. I was surprised to discover that several basis sets very
poorly predict the I2 bond length, with an experimental bond length of
270 pm.

(Basis sets from the EMSL Basis Set Exchange Library)
aug-cc-pVDZ-PP: r =3D 3.3428 =C5
aug-cc-pVTZ-PP: FAILS WITH AN INTERESTING ERROR (see below)

The input file is

ERROR in aug-cc-pVTZ-PP: note the net bond length from the two
calculations. The first adds to about 2.7 =C5 -- very nice -- but the
second calculation, which puts the origin at the center of mass,

Anyone have any idea why the aug-cc-pVxZ-PP basis sets do so poorly?

The 6-311G** basis set, also from EMSL, returns an accurate bond
length of 2.706 =C5.

I've seen many of them, but none of them were done on structures similar to my interest. The structure must be something like a long rope with hanging clothes; here the rope is CH2-CH-CH2-CH style chain, and the clothes are single type of an aromatic ring. Any of you can refer me some studies on polymers like I tried to described above? Thanks.
