TABLE 2.

A comparison of the intensity changes of the dominant amide I bands of RNase A during thermal denaturation at various conditions

Band frequency (cm−1)	Period II*			Period III
	pD 6.0	pD 8.0	pD 8.0 (NaCl)	pD 6.0	pD 8.0	pD 8.0 (NaCl)
1612	—†	↑	↑	—	↑	↑
1618	↑	↑	↑	—	↑	—
1631	↓	↓	↓	—	↘	↘
1638	↑	↑	↑	—	↘	↓

1652	↓	↓	↓	↘	—	↓
1668, 1674	↑	↑	↑	—	—	—
1682	↓	↓	↓	—	↑	↑

^*Period II and Period III are the same as those defined in Fig. 2 and Fig. 4.

^†The symbol “—” represents no significant change, “↑” represents intensity increase, “↓” represents intensity decrease, “↗” represents a slight increase of the band intensity, and “↘” represents a slight decrease of the intensity of the corresponding band that was observed.
