From: Direct observation of ultrafast symmetry reduction during internal conversion of 2-thiouracil using Coulomb explosion imaging

Fig. 6

The molecular coordinate frame is defined by the emission direction of the S atom providing the z axis. The y-z plane is spanned by the emission directions of the S and O atoms. The x axis is perpendicular to the y-z plane. Left: “Top view” projection of the measured momentum-space data of the oxygen atom and the carbon ions. Right: “Side view” projection of the measured carbon ion momenta. The momenta have been normalized such that the magnitude of the sulfur momentum equals 1 for each molecular ionization event.
