[ LPH96 ] 201.663+1.643 , a diffuse H ii region , has been reported to be a candidate for emission from rapidly spinning dust grains .
Here we present Cosmic Background Imager ( CBI ) observations at 26 - 36 GHz that show no evidence for significant anomalous emission .
The spectral index within the CBI band , and between CBI and Effelsberg data at 1.4/2.7 GHz , is consistent with optically thin free-free emission .
The best-fitting temperature spectral index from 2.7 to 31 GHz , \beta = -2.06 \pm 0.03 , is close to the theoretical value , \beta = -2.12 for T _ { e } = 9100 K. We place an upper limit of 24 \%~ { } ( 2 \sigma ) for excess emission at 31 GHz as seen in a 6 \arcmin FWHM beam .
Current spinning dust models are not a good fit to the spectrum of LPH96 .
No polarized emission is detected in the CBI data with an upper limit of 2 \% on the polarization fraction .
