Create the `available_basis_functions` used by lobster.

[hongyi-zhao]

I try to create the available_basis_functions used by lobster as follows:

from mendeleev import element

def get_available_orbitals(elem):
    # Obtain the electron configuration of an element.
    ec = elem.ec.conf

    # Parse the electron configuration to obtain the orbitals.
    orbitals = []
    for orbital in ec:
        orbitals.append(f"{orbital[0]}{orbital[1]}")

    return sorted(orbitals)

with open("available_basis_functions.txt", "w") as f:
    for atomic_number in range(1, 104):
        elem = element(atomic_number)
        orbitals = get_available_orbitals(elem)
        f.write(f"{atomic_number} {elem.symbol} {' '.join(orbitals)}\n")

print("File 'available_basis_functions.txt' has been created.")

In [19]: from mendeleev import element

I wonder whether I can generate the exact same target file by using this package. Any tips/comments will be appreciated.

All the files mentioned above are attached.

availabe_basis_functions.zip

Hey, I'm not quite certain what is the outcome you want to achieve here, do you have some more details?

I hope to get the same output as the following:

It is hard to guess what are those entries in the file whose output you are trying to reproduce. It does not seem these are electronic configurations since entry for Li is 3 Li 1s 2s 2p but there is no 2p electrons for Li, same goes for Na, your files says 11 Na 1s 2s 2p 3s 3p but Na has no 3p electrons.

Regardless I noticed the other difference is ordering of orbitals, where your files follows principal quantum number first whereas mendeleev prints aufbau ordering by default. Here is how you can reorder orbitals to match the output you are showing:

from mendeleev import element
from mendeleev.econf import ORBITALS
 
 for atomic_number in range(1, 104):
    elem = element(atomic_number)
    conf = sorted(elem.ec.conf, key=lambda x: (x[0], ORBITALS.index(x[1])))
    conf_str = " ".join(f"{n}{o}" for n,o in conf) 
    print(f"{elem.atomic_number} {elem.symbol} {conf_str}")

which produces the following

1 H 1s
2 He 1s
3 Li 1s 2s
4 Be 1s 2s
5 B 1s 2s 2p
6 C 1s 2s 2p

It is hard to guess what are those entries in the file whose output you are trying to reproduce. It does not seem these are electronic configurations since entry for Li is 3 Li 1s 2s 2p but there is no 2p electrons for Li, same goes for Na, your files says 11 Na 1s 2s 2p 3s 3p but Na has no 3p electrons.

According to the description here, the availabe_basis_functionsorbital file, which is created by lobster developers, including all potentially available unoccupied orbitals.

which produces the following

I tried the code snippet above, but the results still differ a little from the availabe_basis_functionsorbital file as compared in meld:

It's not sufficiently specified what the required format should be for the file you're trying to produce. Feel free to modify the snippet to fit your needs if that's an option.

This is not really an issue with mendeleev so I'm going to close it. You are welcome to move it to github discussions.

How to move it to github discussions?

[lmmentel]

Here are the github discussions for mendeleev :)

[hongyi-zhao]

What I mean is that it seems like the repository owner can convert an issue into a discussion, instead of creating it from scratch.
