How are the lyman series observed when the dipole selection rule is +/-1 in l change for hydrogen atom ?

The dipole selection rules is about angular momentum quantum number. Only principal quantum number is relevant about Lyman series.

Ok I got it is from 4p l=1 to 1s l=0 for example. Thanks. – user12445 Sep 26 '12 at 6:59
