,Literatur als medial-ästhetisches Ereignis,of the density matrix theory, it is demonstrated that, for each of the three NQR transitions, the (3,3) density matrix can be reduced to a (2,2) matrix, evidently easier to handle. (2,2) rotation matrices are defined for predicting, in a straightforward manner, the system evolution under a rf pulse.

The limitation is given by the noise of the detecting system, mainly a resonant coil tuned at the detection frequency. Here we present a new approach with mixed

Combination of proton—nitrogen level crossing polarization transfer and pulsed spin-locking sequence makes .N NQR in TNT fast and sensitive enough to be used in routine detection of explosives. Enhancement factors for .N NQR li
