Blackbody infrared radiative dissociation spectra of the dimers (a) (dCMP · dGMP − H)− (203 °C, 20 s reaction delay), (b) (dAMP · dTMP − H)− (176 °C, 15 s reaction delay), (c) (dAMP · dCMP − H)− (155 °C, 65 s reaction delay), (d) (dGMP · dTMP − H)− (165 °C, 65 s reaction delay), and (e) (dAMP · dGMP − H)− (165 °C, 30 s reaction delay). Noise peaks indicated by checkmark and harmonic peaks indicated by an asterisk.
