A special accessory allowing identical flushing of several samples with dry nitrogen was used. The samples were thoroughly purified before examination. The very weak carbonyl absorption, after an initial decrease, increases as a sharp band near 1734 cm-1 progressively shifting towards lower wave numbers and then decreases with simultaneous broadening. A corresponding C-H band is seen near 2850 cm-1.
