[DFTB-Plus-User] A question about excited state calculations

Unfortunately, DFTB+ Recipes does not contain examples for Casida-type
TD-DFTB calculations, yet. However, you could go to the test folder and
look up some inputs, as for example in

test/prog/dftb+/timedep/C4H6-Singlet
test/prog/dftb+/timedep/C4H6-Triplet

However, make sure to double check the input parameters when using test
inputs as templates, as the inputs in the test folder do not necessary
represent proper calculations but serve code testing.

  Best regards,

  Bálint
