gammagirl Posted November 1, 2017 Share Posted November 1, 2017 When obtaining an IR spectrum, a secondary amine should exhibit only one N-H stretch, however, when a student ran his sample, two N-H stretches appeared in the spectrum. What could account for this? Link to comment Share on other sites More sharing options...
John Cuthber Posted November 1, 2017 Share Posted November 1, 2017 Poor spectroscopic technique? An impure sample? Link to comment Share on other sites More sharing options...
gammagirl Posted November 1, 2017 Author Share Posted November 1, 2017 I was thinking "A shoulder band usually appears on the lower wavenumber side in primary and secondary liquid amines arising from the overtone of the N–H bending band: this can confuse interpretation."
