Yong Tae Lee, Hak-Ki Lee

이용태, 이학기
새로이 합성한 화합물인 trans-2-butenedial bishydrazone의 AA'BB' 형 NMR 스펙트럼에 나타난 피이크는 모두 2개의 line이 중첩되어 있어서 보통의 방법으로는 internal check이 불가능하다. 5가지 파라미터 δ, K, M, N, L을 점차적으로 변화시켜 이중선의 중간점이 실제 line의 위치에 접근하게끔 함으로써 정확한 line의 위치를 알아내었으며 그 결과로부터 chemical shift와 coupling constant의 값을 구하였다.

The NMR spectrum of newly synthesized compound, trans-2-butenedial bishydrazone is analyzed. It is found that each peak in the AA'BB' spectrum of the compound is consisted of two lines and internal check cannot be accomplished by the usual analytical procedure. Correct line positions are obtained by varying gradually all the parameters, δ, K, M, N, L so that the mid points of the doublets may approach observed line positions and the chemical shifts and the coupling constants of the compound are obtained from the result.
