(color online) Upper: the angular distribution of doubly ionized electrons of C₃H₆ as function of time with the structure of cyclopropane in (a1) linearly, (b1) counter-rotating (ω + 2ω), and (c1) counter-rotating (ω + 3 ω) laser field. Lower: the angular distribution of doubly ionized electrons of C₃H₆ as function of time with the structure of cropene at the end of laser pulse in (a2) linearly, (b2) counter-rotating (ω + 2ω), and (c2) counter-rotating (ω + 3 ω) laser field. The laser wavelength is 1200 nm and the intensity is 30 TW/cm².
