AIMPAC Utilities profil(3) NAME PROFIL - produces profile information of rho or del sq rho along a user defined line in a molecule. SYNOPSIS profil inpfile wfnfile DESCRIPTION The PROFIL program reads information from the inpfile and wfnfile and outputs a file (.pro) containing the distances from the starting point, the coordinates and the corresponding function value (rho or del sq rho). ARGUMENTS inpfile (for example 'hcoh.pfl') The input file describes the type and characteristics of the desired profile. wfnfile (for example 'hcoh.wfn') The wavefunction file contains the primitive basis set and optimized primitive coefficients for the occupied orbitals of the molecular wavefunction. OUTPUT A file with the extention .pro is produced which contains the x,y,x coordinates, distance from starting point, and the function (rho or del sq rho currently) value. This data can be used for external plotting. FORMAT The input to PROFIL is free format with the first seven characters of each card being ignored by the routine and used by the user as labels for ease of use. An example of the input is given here. TITLE: H2O 6-31g** profile plot of rho PARAM: 100 1.0 START: 0.0 0.0 1.0 ENDPT: 0.0 0.0 2.0 FUNC: 1 The cards are used as follows: TITLE: H2O 6-31g** profile plot of rho The first card is a 80 character title card. PARAM: 100 1.0 The first number (integer) of the second card is the desired number of equally spaced segments at which to evaluate the function along the line. The second number (real) is the cutoff value for the function. START: The third card contains the X,Y,Z coordinates of the desired starting point. ENDPT: The fourth card contains the X,Y,Z coordinates of the desired end point. FUNC: The fifth card selects the function which is to be profiled. 1 selects rho, 2 selects del sq rho. EXAMPLES profil hcoh hcoh This requests a calculation of the profile map given the information in hcoh.pfl. Release 2.0 AIMPAC profil(3)
