Chemical shift anisotropy amplification with high amplification factor and improved sensitivity
An improved version of the recently proposed chemical shift anisotropy amplification experiment is described. The original experiment correlates a fast magic angle spinning spectrum in the ω 2 dimension with a sideband pattern in ω 1 in which the intensities mimic those for a sample spinning at a fr...

| description | An improved version of the recently proposed chemical shift anisotropy amplification experiment is described. The original experiment correlates a fast magic angle spinning spectrum in the
ω
2 dimension with a sideband pattern in
ω
1 in which the intensities mimic those for a sample spinning at a fraction of the rate
ω
r/
N. Advantages of the experiment include the use of standard methods to extract the principal tensor components from the
ω
1 sideband patterns and the small number of
t
1 increments required. The improved version described here permits large amplification factors
N to be obtained without resort to prohibitively long sequences of π-pulses and allows sensitivity to be maximized by eliminating the need to store the magnetization along the
z-axis for
t
1. Amplification factors up to 32 are demonstrated experimentally. |
