ADDITIONS AND CORRECTIONS 2007, Volume 111C Anni Siitonen, Henrik Kunttu, and Mika Pettersson*: Temperature Dependence of Electronic Transitions of SingleWall Carbon Nanotubes: Observation of an Abrupt Blueshift in Near-Infrared Absorption On page 1891, we have found an error in eq 1 of our recent paper. This equation describes the temperature dependence of electronic transition energies and was incorrectly published as
pω ) - 1] [ (2kT
E(T) ) E(0) - Spω coth ) E(0) - Spω
[ ( )] 2 pω exp kT

The corrected equation is
pω ) - 1] [ (2kT
E(T) ) E(0) - Spω coth ) E(0) - Spω
[

2 pω exp -1 kT

This change leads to slightly different values for the frequencies of the coupled phonon as obtained by fitting with eq 1 the data in Figure 5. For bands 1 and 2, the previously obtained frequencies of 255 and 244 cm-1 are changed to 225 and 221 cm-1, respectively. This change does not affect any other data or conclusions reached in the paper. 10.1021/jp0747050 Published on Web 07/11/2007
