Portions of the 500.1-MHz gradient-enhanced two-dimensional COSY spectrum of S. suis serotype 1 CPS in 33 mmol/liter phosphate buffer, pD 8.0, in D2O at 65 °C. 512 increments of 1024 complex data points were acquired in magnitude mode with a digital resolution of 4.9 Hz/point in the t2 dimension and 9.8 Hz/point in the t1 dimension. The t2 dimension was processed by multiplication with an unshifted sine bell window function and Fourier transform, and the t1 dimension was processed by Zhu-Bax linear prediction to 1024 points, multiplication with an unshifted sine bell window function, Fourier transform, and magnitude calculation. The f2 trace corresponds to the one-dimensional spectrum (see Fig. 2A).
