Dear Prasun, There are a number of web sources for f' and f'' and the International Tables Vol C also have it. However the one I like the most because it shows the information in a graphical display additionally to the numbers themselves is the program fprime by VonDreele that you can obtain from ccp14. Hope this helps Leo
