The phase-wiggled two-pulse phase modulation or PW-TPPM, a recently formulated scheme functions effectively for heteronuclear dipolar decoupling in nuclear magnetic resonance of static solid samples [R. Fu, Chem. Phys. Lett. 483, 147, 2009]. In PW-TPPM, the two pulses within each TPPM element have different alternating phase angles and thus these elements become phase-wiggled. In this communication, a modified PW-TPPM scheme is presented, generated by varying pulse durations of the parent PW-TPPM in a way similar to SWf-TPPM (Swept-frequency two-pulse phase modulation) decoupling sequence. The rationale was to find the impact of the tangential variations in pulse durations on the efficiency of PW-TPPM decoupling scheme. The performance of the newly formed sequence, termed as PWSWf-TPPM, is studied in liquid crystals and rotating solids.
