Fig. 5. — Traces of 2D IR correlation spectra. (a) Least-squares fit to the 12 cm⁻¹-wide trace along the ω_t axis of the heterodimer (G*₇₉ + G**₇₉) − 0.25G**₇₉ as described in the text (thick solid line), the fit omitting the cross-peak (thick dashed line), the difference between the solid and the dashed line (thin solid line), and the cross-peak response from least-squares-fitting the whole spectral region between the two vertical lines (thin dotted line). (b) Comparison between the ¹³C¹⁸O trace of G*₇₉ + G**₇₉ (solid line) and the control sample G*₉₄ + G**₇₉ (dashed line).
