How to take the Laplace transform of 1/f(t)?

Question

I know I am streching it... But still: Is there any general property of the Laplace transform of 1/f(t)? For example, one general property of a Laplace transform, from t-->s, is that

LT[t^nf(t)]=(-1)^nF^(n)(s) 

What can we say in the same spirit about LT[1/f(t)]?

Thanks.
