WebApr 4, 2003 · RdFreq Perform frequency-dependent CPHF, reading in the frequencies for the electromagnetic field perturbation. The default is a static frequency calculation. This option causes the desired frequency to be read from the input stream. The default units for this value are Hartrees. WebJul 8, 2004 · Computing pre-resonance Raman intensities (with CPHF=RdFreq) will approximately double the job's CPU requirements. While frequency calculations can be done using very modest amounts of memory, performance on very large jobs will be considerably better if enough memory is available to complete the major steps in one …

Actually, there is a hint on the mentioned pages of the Reference – the keyword field reads: WebGaussian 09 keywords freq=raman, cphf=rdfreq and polar were used to compute the hyperpolarisability. Here the hyperpolarisability tot is given as the function of the tensor and is the hyperpolarisability parallel to the ground state CT direction. tot

WebI have read that the essential keywords to include for such request are the #polar and CPHF=RdFreq. However, where exactly do I specify the frequency in the input stream? Here is my route section (I'm welcoming any comments if there's a mistake in this command). #p polar cphf=rdfreq b3lyp/6-31g(d) geom=connectivity
WebAt least in Gaussian 09, for some methods, there is the possibility to calculate the Raman scattering activities for a certain incident light frequency through cphf=rdfreq. As far as I know, the latter would give me the dynamic Raman activities and whenever I don't enter the incident light frequency I will get static Raman activities. cco hiringhttp://theochemlab.asu.edu/teaching/chm543/Lab7.pdf cco hirslandenWebFind Out How. “ Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances. — 1st Amendment to the United States Constitution. busy b\u0027s herne bayWebJun 20, 2024 · Polar.
