I want to use both in the same document (they are sometimes used to symbolize different sorts of negation). How can I redefine \sim so that it gets the same spacing properties as \lnot?

@N.N.: As @egreg suggests, use a different name. For example, \newcommand{\simnot}{{\sim}}. Note the double braces.

as noted in comments to another question, the class of \lnot is ultimately \mathord, which is equivalent to what you've got here. but it's never a bad idea to be excruciatingly specific: \newcommand{\varlnot}{\mathord{\sim}}
