Statistical analysis of unit activity in the cat motor cortex

Optical Properties of 3,4,9,10-perylenetetracarboxylic dianhydride/copper phthalocyanine superlattices

“…The peak positions for all samples indicate that the films consist of ␣-phase CuPc while the CuPc in the pellet exhibits ␤-form characteristics. 14,15 According to Debe 16 the 722 and 750 cm −1 peaks correspond to the out-of-plane vibrations of the CuPc molecule while the peak at 753 cm −1 and all bands above 800 cm −1 are due to molecular in-plane vibrations. Considering p polarization, the 722 and 750 cm −1 peaks have derivative like shapes or are pointing downwards.…”

Oxygen reduction reaction in acid medium at iron phthalocyanine dispersed on high surface area carbon substrate: tolerance to methanol, stability and kinetics

“…After a few minutes of chronoamperometry in O 2 -saturated acid electrolyte, the IR spectrum changed. The localisation of the main absorption bands for the last recorded spectrum are also listed in Table 2 together with results obtained by Sidorov and Kotlyar [42] and Sammes [43] for H 2 Pc. Again, the experimental data fit well.…”

“…4(b). The wavenumbers corresponding to the maximum of the IR absorption bands found in the first spectrum are reported in Table 1 together with those recorded by Sidorov and Kotlyar [42] for comparison. Apart from the bands located at wavenumbers at 1201 and 1395 cm À1 which are present in our spectrum and were not detected by Sidorov and Kotlyar, the agreement in the experimental results is very good since the difference in band positions are in most cases within 4 cm À1 , which is the resolution of the FT-IR set-up.…”

Synthesis and Properties of Extracomplexes of Tetrasubstitued Phthalocyanines

“…The absorption characteristic of the phthalocyanine macroring is observed at 7303760, 9503965, 102031095, and 11183 1180 cm !1 [23]. At the same time a number of new bands connected with certain functional substituents [24] appear in the spectra.…”
