Yes, free nucleoside triphosphates absorb at around 260nm too. Here's the info 
from the back of the Promega protocols guide:

      Absorbance maximum nm (pH7)     Absorbance for 1M solution

dATP         259                               15 200

dCTP         271                                9 300

dGTP         253                               13 700

dTTP         267                                9 600
