Relationship between the D 2.72/D 2.79 ratio and the D 2.76/D 2.90 ratio. A broken line shows a gap at an arbitrarily D 2.76/D 2.90 value of 0.8. The most hydrous chondrites (1, 2) and Winselwan (4), which has a characteristic narrow peak at 2.72 μm, plot above the line. On the other hand, the other chondrites are clustered below the line. Labels: 1 = Murchison, 2 = Murray, 3 = Y-793321, 4 = Jbilet Winselwan, 5 = Y 982086, 6 = Y 980115, 7 = Y-86720, and 8 = B-7904
