Excitation bandwidth for a shaped pulse

Excitation bandwidth for a shaped pulse

Hi all,I have a small question on excitation bandwidth for shaped pulses. In many of the literature, the field strength ( nu (Hz) = Gamma * B1/(2 * pi)) of the shaped pulse is specified, so i use it to determine the pulse width (tp) using the relations,

omega * t_p = theta; & Omega = 2 * pi * nu

t_p= theta/(2 * pi * nu) [sec]

On knowing 't_p' value, i can use 'shape tools' available in Bruker to calculate the power level of the shaped pulse in comparison to a 90 degree hard pulse. My question is-- is the nu(Hz) value mentioned in the literature, the actual excitation bandwidth of the shaped pulse?

Thank you!

[U. of Ottawa NMR Facility Blog] Shaped Pulses Shaped Pulses Shaped rf pulses are used frequently in modern NMR experiments for selective excitation and more efficient inversion. The figure below shows some of the pulse shapes in the Bruker shape library measured with an oscilloscope on an AVANCE III console.

[U. of Ottawa NMR Facility Blog] Excitation Profiles for Shaped Pulses Excitation Profiles for Shaped Pulses Shaped pulses are very commonly used for selective excitation and nonselective inversion in a large number of NMR pulse sequences. The frequency domain excitation profile of a radio frequency pulse is the Fourier transform of the time dependent pulse shape and determines the width, uniformity and phase of the frequency spectrum excited. Since time and frequency are reciprocals of one another, short rf pulses have very wide excitation profiles and long rf pulses have very narrow selective excitation profiles. In a previous BLOG post the excitation...	nmrlearner	News from NMR blogs	0	01-21-2011 03:31 AM
