Continuous modulated pulsed power

The easiest way to reduce the amplitude of TOCSY cross peaks in the ROESY spectra is to record a spectrum with minimal spin-lock power [23]. The other possibility is to modulate the frequency of the spin-lock field [25]. However, the most convenient way is to apply a series of 180° pulses instead of a single continuous-wave pulse during the mixing time, as is done in the T-ROESY experiment. Figure 4(D) shows the T-ROESY spectrum of cyclo(Pro-Gly) recorded with = 300 ms. Although the... [Pg.286]

Experimental and theoretical evidence indicates that pulsed fields cannot have greater effects than continuous fields of the same average power (51). Hence, modulation is not expected to have special effects. [Pg.125]
