I'm a total Mathematica newbee so please bear with me :-). I'm trying to let 
Mathematica analytically evaluate a second order derivative for me. The 
function has several parameters with some of them being of 
"Quaternion-type". I want to instruct Mathematica that the commutative rule 
doesn't apply when evaluation the function. Is that possible? Thanks in
