Yes: 

%Q["abc 'def]

and

%["abc 'def]

create a string which can contain string interpolation:

%Q[{1+1}]
=> "2"

%q["abc 'def]

creates a string without string interpolation:

%q[#{1+1}]
=> "#{1+1}"

You can replace the [] with (), {} or <> or with any non alphanumeric 
character (that is any character excluding letters and digits):

%q{"abc"}
%q!abc!

I hope this helps
