Hi Amrish,

As far as I know irrespective of software, PDOS is same. Density of States of a particular fragment in a molecule is nothing but partial/projected density of states.

Konrad Gruszka

PDOS or projected density of states is generally speaking number of available states for electrons to occupy projected on atomic orbitals. So by doing PDOS you can see which shell (s,p,d,f) and orbital for specified atom has the biggest share in TOTAL DOS for your crystalline phase or molecule. This is little bit oversimplified, but in general the simplest explaination.

Amrish Sharma

thanks konrad and sai for your kind answers
