The Specific Heat of Carbon Dioxide—Correction

Extract

In a recent paper in these Proceedings the writer suggested the possibility of a transition from one molecular form to another in CO₂. The suggestion is embodied in the equation (10) and the resulting specific heats for low temperatures given. He greatly regrets that it was not till after those results were published that he found they gave a high and altogether impossible maximum in the specific heat curve for higher temperatures before it returns to the neighbourhood of the unmodified curve C_v′.
