High-harmonic generation was used to probe the spectral intensity and phase of recombination-dipole matrix element methyl chloride (CH3Cl), revealing a Cooper minimum (CM) analogous 3p CM previously reported in argon. The structure altered response group delay (GD) emitted harmonics, revealed only through careful removal all additional contributors GD. In characterizing GD dispersion, also known as “attochirp” we additionally present most complete validation date commonly strong-field approximation for calculating GD, demonstrating correct scaling extending its usefulness simple molecules.
