(a) Spectrally selective, minimum phase radiofrequency pulse designed to excite ${HCO}_{3}^{-}$ (160 ppm) while leaving [1‐¹³C]pyruvate (170 ppm) unexcited. (b) Experimentally measured spectral profiles using thermally polarized, 5 M ¹³C urea show good agreement with Bloch simulation (top: real and imaginary response; bottom: magnitude response) with residual errors likely due to RF amplifier nonlinearities.
