I believe the answer is:

islamabad

I'm a little stuck... Click here to teach me more about this clue!

'some capital' is the definition.
(Islamabad is an example)

'one bang on a spot to raise' is the wordplay.
'one' becomes 'I' (Roman numeral).
'bang' becomes 'slam' (synonyms).
'on' is a charade indicator (letters next to each other).
'a spot' becomes 'ad'.
'to raise' becomes 'ab' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ad' put after 'ab' is 'abad'.
'i'+'slam'+'abad'='ISLAMABAD'
