1
1050 cm
belongs to C – N stretch, 1640 cm
belongs to C =N stretch
1640 cm
belongs to C – N stretch, 1050 cm
belongs to C =N stretch

Why?
because a higher frequency absorption corresponds to a stronger bond
because frequencies absorption lower than 1600 cm
-1
always account for single bonds
because frequencies absorption higher than 1600 cm
-1
always account for double bonds
because a higher frequency absorption corresponds to a weaker bond
