Product operator descriptions of INEPT and RINEPT NMR spectroscopies for ISn (I=1/2, S=3/2) spin systems

Product operator descriptions of the 2D DEPT J-resolved NMR experiment for weakly coupled ISn (, ; n=1, 2, 3) spin systems

“…(21) This expression shows that the 2D DEPT J -resolved NMR signal for the IS spin system depends on sin θ and gives four signals at the coordinates (3πJ/2, I ), (πJ/2, I ), (−π J/2, I ) and (−3π J/2, I ) with an intensity distribution of (3:−1:−1:3), which arises due to the polarization transfer in the pulse sequence [27].…”

“…Likewise, the product operator theory of the 2D DEPT J -resolved NMR experiment for weakly coupled I S n (I = 1 2 , S = 1; n = 1, 2, 3) spin systems has been reported [22]. In our previous studies, analytical descriptions of some NMR experiments have been presented using the product operator theory for weakly coupled I S n (I = 1 2 , S = 3 2 , 5 2 ; n = 1, 2, 3) spin systems [23][24][25][26][27][28].…”

A Product Operator Theory of DEPTQ NMR Spectroscopy for ISn(I = 1/2; S = 1; n = 0, 1, 2, 3) Spin Systems

“…The product operator theory as a quantum mechanical method is widely used for analytical description of multipulse NMR experiments on weakly coupled spin systems in liquids having spin-1/2, spin-1 and spin-3/2 nuclei [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. This method not only allows the confirmation of experimental results but also offers to make some experimental suggestions on NMR experiments.…”

The product operator description of INEPT experiments forIS (I=1/2;S=5/2) spin systems and its applications to microcline and TMP-AlCl3 complex in NaX zeolite

“…Bahqeli and A. Tokath erator formalista to the INEPT pulse sequence for two-spin IS systems by using the single-spin operator basis. The INEPT NMR spectroscopy for weakly coupled IS, (1 = 1/2; S = 1/2, 1, 3/2 with n = 1, 2, 3) spin systems has been described analytically by using the product operator theory asa quantum mechanical method [10][11][12][13].…”
