Tube metal indication temperature

For measuring hot (1,000-1-°F) furnace flue-gas temperatures, a velocity thermocouple should be used (see Chapter 15). Using an ordinary static thermocouple will indicate a lower-than-actual temperature due to the effects of reradiation from the thermocouple. Furnace tube metal temperatures are approximated visually ... 

CF2)2C2(AsMe2)2 (tfars), in acetonitrile (sealed tube, eight days at 100 °C, six months at room temperature) yields [ZrCl3(tfars)] -MeCN as a brown solid. A weak IR band at 2255 cm-1 indicates that the acetonitrile is not coordinated to the metal. This compound is a nonelectrolyte in acetonitrile and exhibits a magnetic moment at room temperature of 1.73 BM. It appears to be the first magnetically dilute zirconium(III) complex to have been reported.20...
