## Abstract Composite pulses that compensate for resonance offset and electric field gradient inhomogeneity are proposed for broadband excitation of pure nuclear quadrupole resonance systems in powders. The excitation band width of the composite pulse sequences was obtained with a numerical calcula
We show how the single-mode Floquet theory, valid only for sinusoidal field problems, may be generalized to a coupled quasienergy (or dressed-) states formalism, allowing non-perturbative treatment of multiphoton excitation of multilevel quantum systems driven by non-sinusoidal coherent pulse fields
## Abstract The application of shaped pulses, e.g. TOPHAT and hyperbolic secant, for the semiβselective excitation of the imino ^1^H resonances of duplex DNA and RNA in aqueous solution is explored. The excitation profiles for the shaped pulses are calibrated on a sample containing a mixture of A:U
